Isochronous mass spectrometry at the RIKEN Rare-RI Ring facility

D. Nagae et al.

Phys. Rev. C 110, 014310 (2024) - Published 3 July, 2024

Nuclear masses are among the most significant observables to elucidate nuclear structure and its evolution with proton and neutron number as well as nucleosynthesis in the cosmos. This is especially so in exotic nuclei where masses will be among the first observables measured for new nuclei. Yet, such measurements are extremely difficult due to the short lifetimes and low production yields at rare isotope beam facilities. The present work describes the Rare-RI Ring facility, an isochronous storage ring at RIKEN, and the first commissioning measurements to establish its capabilities. The full identification of each ion before injection into the storage ring and the measurement time of about 1 ms are excellently suited for measuring masses of the most exotic nuclei, promising a breakthrough in the precision mass spectrometry of extremely rare short-lived radionuclides.

Precise neural network predictions of energies and radii from the no-core shell model

Tobias Wolfgruber, Marco Knöll, and Robert Roth

Phys. Rev. C 110, 014327 (2024) - Published 25 July, 2024

Ab-initio calculations of atomic nuclei have revolutionized nuclear structure physics. Yet challenges remain, not least the reliable calculation of nuclear radii. In a concurrent development, modern machine-learning algorithms have excelled in a variety of computational tasks such as pattern recognition and interpolation. The authors have applied artificial neural networks (ANNs) to the extrapolation of no-core shell model calculations to infinite model spaces, effectively circumventing their computational limitations. In particular, the results show that min-max normalization, a common technique in machine learning, leads to the best results for radii. These advances offer hope that the ANN architecture is capable of handling other observables such as electromagnetic moments and transition strengths.

Ab initio investigation of the Li7(p,e+e)Be8 process and the X17 boson

P. Gysbers, P. Navrátil, K. Kravvaris, G. Hupin, and S. Quaglioni

Phys. Rev. C 110, 015503 (2024) - Published 10 July, 2024

Recent observations by the ATOMKI Collaboration of anomalies in electron-positron pair production following proton capture on light nuclides has led to the postulation of a new boson with mass around 17 MeV. Here a team of scientists from the United States, Canada, and France presents the most detailed microscopic calculations to date of the proton capture reactions, and is unable to find a conventional explanation for the anomalies. While these calculations do not confirm the existence of the so-called X17 boson, they provide strong motivation for continued and independent experiments to investigate the ATOMKI results. Further refinements of the calculations may provide theoretical constraints for future data.

Strength measurement of the Eαlab=830 keV resonance in the Ne22(α,n)Mg25 reaction using a stilbene detector

The 22Ne + α reaction has significant impact at the end of the core helium burning phase in red giant stars. Radiative α capture, (α,γ), heats the plasma while the (α,n) reaction provides neutrons for the weak s process; their interplay determines the efficiency of the latter as a neutron source. The authors measure the strength of the resonance at Eα,lab=830 keV in the 22Ne(α,n)25Mg reaction. This resonance dominates the reaction rate for both the 22Ne(α,n)25Mg reaction and the competing 22Ne(α,γ)26Mg radiative capture at temperatures larger than 0.25 GK. As a crucial step, the authors characterize the stilbene neutron detector, where relevant information on the neutron energy is retained, and evaluate the possible sources of neutron background in their measurement. The results significantly improve the characterization of the astrophysically impactful 830 keV resonance.

Multichannel constraints on the Li6(p,γ)7Be reaction

Phys. Rev. C 110, 015802 (2024) - Published 9 July, 2024

Nucleosynthesis during the Big Bang (BBN) can produce the lightest elements, including lithium, but the observed abundance of lithium in old stellar populations is much less than that predicted from BBN. To solve this so-called “lithium puzzle”, it had been postulated that a previously unobserved resonance in 7Be could deplete lithium through resonant proton capture on 6Li and thus account for the deficit. The authors performed a detailed study using information from all possible reactions that could be influenced by such a state, utilizing the stringent constraint imposed by the unitarity of the scattering matrix. They conclude that the postulated 3/2+ state in 7Be is highly unlikely, but they also suggest that additional radiative capture data are required to solve lingering discrepancies.

Ab initio computations of strongly deformed nuclei near Zr80

B. S. Hu, Z. H. Sun, G. Hagen, and T. Papenbrock

Phys. Rev. C 110, L011302 (2024) - Published 24 July, 2024

Atomic nuclei near mass 80 with approximately equal numbers of protons and neutrons are known to be strongly deformed while different shapes coexist in the same nucleus. These phenomena have challenged nuclear models but are also an opportunity to test the advances in theoretical approaches. The authors perform ab-initio coupled-cluster calculations for even-even nuclei near neutron-deficient 80Zr, including calculations of B(E2) transitions, using chiral NN and NNN forces. The results adequately describe shape coexistence even if they cannot unambiguously determine ground-state shapes. The calculations are a significant step forward in mass number for ab-initio computations of deformed nuclei.

Recent observations by the ATOMKI Collaboration of anomalies in electron-positron pair production following proton capture on light nuclides has led to the postulation of a new boson with mass around 17 MeV. Here a team of scientists from the United States, Canada, and France presents the most detailed microscopic calculations to date of the proton capture reactions, and is unable to find a conventional explanation for the anomalies. While these calculations do not confirm the existence of the so-called X17 boson, they provide strong motivation for continued and independent experiments to investigate the ATOMKI results. Further refinements of the calculations may provide theoretical constraints for future data.

The 22Ne + α reaction has significant impact at the end of the core helium burning phase in red giant stars. Radiative α capture, (α,γ), heats the plasma while the (α,n) reaction provides neutrons for the weak s process; their interplay determines the efficiency of the latter as a neutron source. The authors measure the strength of the resonance at Eα,lab=830 keV in the 22Ne(α,n)25Mg reaction. This resonance dominates the reaction rate for both the 22Ne(α,n)25Mg reaction and the competing 22Ne(α,γ)26Mg radiative capture at temperatures larger than 0.25 GK. As a crucial step, the authors characterize the stilbene neutron detector, where relevant information on the neutron energy is retained, and evaluate the possible sources of neutron background in their measurement. The results significantly improve the characterization of the astrophysically impactful 830 keV resonance.

Nucleosynthesis during the Big Bang (BBN) can produce the lightest elements, including lithium, but the observed abundance of lithium in old stellar populations is much less than that predicted from BBN. To solve this so-called “lithium puzzle”, it had been postulated that a previously unobserved resonance in 7Be could deplete lithium through resonant proton capture on 6Li and thus account for the deficit. The authors performed a detailed study using information from all possible reactions that could be influenced by such a state, utilizing the stringent constraint imposed by the unitarity of the scattering matrix. They conclude that the postulated 3/2+ state in 7Be is highly unlikely, but they also suggest that additional radiative capture data are required to solve lingering discrepancies.
