Abstract
The electromagnetic decay properties of levels in
100Mo have been studied by Coulomb-excitation yield measurements and lifetime determinations. For the yield measurements thin targets of
100Mo were bombarded with beams of
16O and
32S at 42 and 89 MeV incident energy, respectively. The emitted γ-rays were observed in coincidence with particles detected in a position-sensitive gas proportional counter. In a separate experiment the recoil-distance method was used to determine the lifetimes of levels in
100Mo excited in the bombardment of a thin target with a
58Ni beam of 185 MeV energy. Matrix elements for the observed transitions were deduced from the particle-gamma coincidence yields and from the measured lifetimes. A consistent set of results was obtained. The collective E2 transition rates determined from the analysis were found to be in remarkably good agreement with the predictions of the interacting boson model with configuration mixing.
