Abstract
High-spin states in 74As were studied using the 74Ge(4He, 1p3n) reaction at beam energies of 58.6 and 62.6
MeV. Two positive- and one negative-parity bands have been identified in 74As. The two positive-parity bands are
interpreted as chiral doublet bands, which is supported by the triaxial particle rotor model. Three electric dipole
transitions linking the yrast positive- and negative-parity bands were also observed in this work, suggesting the
existence of octupole correlations in 74As.
