Abstract

The lifetime of the (11/2(+)) state in the band above the proton-emitting (3/2(+)) state in Cs-113 has been measured to be tau = 24(6) ps from a recoil-decay-tagged differential-plunger experiment. The measured lifetime was used to deduce the deformation of the states using wave functions from a nonadiabatic quasiparticle model to independently calculate both proton-emission and electromagnetic gamma-ray transition rates as a function of deformation. The only quadrupole deformation, which was able to reproduce the experimental excitation energies of the states, the electromagnetic decay rate of the (11/2(+)) state and the proton-emission rate of the (3/2(+)) state, was found to be beta(2) = 0.22(6). This deformation is in agreement with the earlier proton emission studies which concluded that Cs-113 was best described as a deformed proton emitter, however, it is now more firmly supported by the present measurement of the electromagnetic transition rate.
