Chirality and octupole correlations in As 74. Physical Review C, 106(6), p.064302.2469-9985http://hdl.handle.net/10566/9147High-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.enCollective levelsCollective modelsNuclear structure & decays59 ≤ A ≤ 89Spectrometers & spectroscopic techniquesArticle
