Abstract

High-spin states in As76 have been observed for the first time by using the He4+Ge74 reaction at beam energies of 58.6 and 62.6 MeV. Two positive-parity and three negative-parity bands have been found in As76. The two positive-parity bands with πg9/2 - νg9/2 configurations are tentatively interpreted as chiral doublet bands, which are supported by triaxial particle rotor model calculations. The electric dipole transitions linking the yrast positive- and negative-parity bands are also observed in this work, implying the possible presence of octupole correlations in As76.
