Decay ofCs134and the Level Scheme ofBa134

The energy (in keV) and the relative intensity of the gamma rays following the decay of ${\mathrm{Cs}}^{134}$ have been measured as 475(1.1), 563(9), 569(11), 605(98), 800(93), 1038(1.1), 1168(2.7), and 1367(3.5) with the help of the various scintillation spectrometry techniques. No gamma rays of energy 960, 1570, 1640, 1770, and 1970 keV reported earlier by certain workers could be detected. In addition to the already established 86 keV (26%) and 655 keV (71%) end-point beta rays, three beta rays of end points and intensities 1453 keV (0.13%), 892 keV (0.7%), 410 keV (2.1%) were confirmed by careful measurement with the help of a beta-ray spectrometer. The $K$-conversion coefficient of the gamma rays and the $log\mathrm{ft}$ value of the beta rays were obtained. The measurements established more firmly the decay scheme including the spin and parity assignments to the various levels.
