摘要：

Lifetime measurements of the excited states of 193Ir were carried out by delayed coincidence measurements between the beta spectrum of 193Os and the conversion lines that de-excite the levels, using a double-lens coincidence spectrometer. The mean lifetimes of the 139 keV and 460 keV levels were determined as τ = 127 ± 13 psec and τ = 27 ± 7 psec, respectively. The upper limits for the mean lifetimes of the 180 keV, 361 keV, 712 keV and 558 keV levels were found to be τ ≦ 50 psec, τ ≦ 130 psec, τ ≦ 160 psec and τ ≦ 300 psec, respectively. The latter limit was deduced from delayed coincidence measurements between the beta spectrum and the gamma rays. The experimental absolute transition probabilities and static moments deduced from the present work and from previous investigations,could be accounted for by describing the 73 keV, 139 keV, 180 keV, 357 keV and 460 keV states by particle-excited core wave functions. © 1968.
