Yrast and near-yrast excitations up to high spin in 48100Cd52

The gamma decay of excited states in the nucleus 100Cd, which is two proton holes and two neutrons away from doubly magic (N=Z=50) 100Sn, has been studied with the Gammasphere array following the 46Ti(58Ni,2p2n) reaction at 215 MeV. Residues were identified by detection of evaporated charged particles in the Microball CsI array, by neutron detection in a set of liquid scintillator detectors, and by a tag on the delayed gamma-ray decay of the known 8+ isomeric state. The level scheme has been extended up to 20ħ in angular momentum and to nearly 10 MeV in excitation energy. The results are compared with shell-model calculations.
