Abstract

The ground state of radioactive Ba133 was correlated with metastable state of Ba133*. It was found that after K-electron capture occurs, there are two excited states in Cs133* 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 NeNγ0.02 and 0.34, respectively. The change in angular momenta of the excited states of Cs133* due to emission of 320-kev and 85-kev photons is calculated to be L=2 and L=1. 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.
