FINGERPRINTS OF REFLECTION ASYMMETRY AT HIGH ANGULAR-MOMENTUM IN ATOMIC-NUCLEI

The reflection asymmetric phase transition in nuclei at high angular m omentum is analyzed in the framework of the cranked Hartree-Fock-Bogol iubov approximation, with the Gogny interaction, using approximate par ity projection before variation. The N = 88 isotones are studied and o ur results compared with experimental data. Good agreement is found fo r the energy splitting of the even and odd parity states and B(EI) tra nsition probabilities. Differences on intrinsic deformations, dipole m oments, and pairing energies between odd and even parity states found at low spin disappear with increasing angular momentum.
