The gamma rays of Cs/sup 133/ following the electron-capture decay of Ba/ sup 133/ were studied using a coincidence scintillation spectrometer. Gamma rays with the following energies were observed: 386,356,301, 176, (220), 162, 82, 80, and 54 kev. The energies of the nuclear levels of Cs/sup 133/ with their spins and parities are: ground state (7/2+), 82 capture transitions and their relative intensities are as follows: (a) to the 418-kev level, 76% (b) to the 383-kev level, 11% (c) to the 162-kev level, 13%. In the decay of Xe/sup 133/, 1.5 plus or minus 1.0% of the beta transitions was observed to go to the 162-kev level in Cs/sup 133/ and the remaining go to the 82-kev level. (auth)
