Abstract
The ground state of radioactive was correlated with metastable state of . It was found that after -electron capture occurs, there are two excited states in corresponding to observed two photons of 320±10 kev and 85±5 kev. Both gamma-rays are converted. The conversion ratios for these two photons are , respectively. The change in angular momenta of the excited states of due to emission of 320-kev and 85-kev photons is calculated to be and . Attempts to observe a third gamma-ray of Å405 kev did not yield positive results. The calculated intensity of the 405-kev photon, if it is emitted, is estimated as equal to 0.001 of the intensity of the 320-kev photon.
