Evidence of octupole correlation in ⁷⁹Se

NUCLEAR REACTIONS ⁷⁶Ge(⁹Be, 2nα)⁷⁹Se, E≈31 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(DCO), γγ(θ)(ADO ratios), γγ(linear polarization), T_1/2 of levels by DSAM using INGA array of 14 Compton-suppressed clover detectors at the TIFR Pelletron Linac Facility. ⁷⁹Se; deduced high-spin levels, J, π, multipolarities, multipole mixing ratios, B(M1), B(E2), B(E1)/B(E2) ratios, intrinsic dipole moments, octupole correlation; calculated potential energy surface in (β₂₀, β₃₀) plane based on the covariant density functional theory. Comparison of measured transition probabilities with reflection asymmetric triaxial particle rotor model (RAT-PRM) calculations.
