The decay of /sup 120/Xe

The decay scheme of 40 min /sup 120/Xe has been investigated using isotopically separated sources produced by the ISOLDE facility at CERN. A total number of 202 gamma -transitions has been observed in this decay; 188 of them have been placed in a level scheme involving 34 excited states in /sup 120/...

Sumario:The decay scheme of 40 min /sup 120/Xe has been investigated using isotopically separated sources produced by the ISOLDE facility at CERN. A total number of 202 gamma -transitions has been observed in this decay; 188 of them have been placed in a level scheme involving 34 excited states in /sup 120/I. Most of these levels are based on the results of gamma - gamma coincidence experiments with two Ge(Li) detectors. Internal conversion coefficients have been obtained with a Si(Li) detector and a magnetic spectrometer. The half-life of 4 low- lying levels in /sup 120/I has been measured by delayed coincidence techniques. From these measurements, partial half-lives for some transitions have been deduced and are compared with the single- particle estimates. Two E2 transitions are strongly enhanced. (24 refs).
