Abstract
Gamma rays from have been studied with Gammasphere and the Fragment Mass Analyzer using reactions induced by a beam on a target. The data have been used in combination with information from deep-inelastic reactions of beams on a thick target at an energy about above the Coulomb barrier. The level scheme was expanded considerably, and the lifetimes of some of the identified states were determined for the first time. The excitation of two protons and two neutrons outside the core provide new tests of effective interactions in the full -shell model space. The positive-parity states in were compared to theoretical predictions obtained with the GXPF1A, FPD6, and KB3G effective interactions. The comparisons favor, to a degree, the results computed with the GXPF1A interaction.
