Description

The results of measurements of the gamma-ray and conversion-electron singles and coincidence spectra from the decay of the 122 s 121mCs and the 155 s 121gCs to levels of 121Xe are reported. The M3 multipolarity of the 68.5 keV isometric transition in 121Cs has been deduced. Numerous low-lying levels below 1.6 MeV excitation energy are found. A negative-parity level at 355.9 keV is observed for the first time. The results supplement the low lying energy level systematics in odd-A xenons. A comparison is made with the N=67 barium isotone.
