Structure of ⁸³As, ⁸⁵As, and ⁸⁷As: From semimagicity to γ softness

NUCLEAR REACTIONS ⁹Be(²³⁸U, X)⁸³As/⁸⁵As/⁸⁷As, E=6.2 MeV/nucleon; measured Eγ, Iγ, (particle)γ-coin, γγ-coin using the VAMOS++ spectrometer for particle detection and AGATA array for γ radiation at GANIL facility. ^83,85,87As; deduced levels, J, π, collectivity in a prolate deformed, γ-soft regime in the open shell nuclei. Comparison with shell-model calculations. Systematics of energies of 9/2+ states in ^83,85,87,89As, ^85,87,89,91Br, ^87,89,91,93Rb, ^89,91,93,95Y from experimental data and large-scale shell-model calculations.

NUCLEAR STRUCTURE ^85,87As; calculated levels, J, π, potential energy surfaces (PES) in (β, γ) planes, wave functions amplitudes in K-quantum numbers. Large-scale shell-model calculations, SU3 symmetries, and beyond mean-field calculations.
