Shape isomerism and shape coexistence effects on the Coulomb energy differences in the N=Z nucleus ⁶⁶As and neighboring T=1 multiplets

NUCLEAR REACTIONS ⁴⁰Ca(³²S, npα)⁶⁶As, E=90 MeV; measured Eγ, Iγ, γ(θ), angular asymmetry ratios, (particle)nγ-, γγ-coin, particle and neutron spectra, isomer half-life using Gammasphere array at ATLAS facility. ⁶⁶As; deduced levels, J, π, shape isomer, B(E2), isospin=1 states, Coulomb energy differences (CED); calculated neutron single-particle energies. Breaking of isospin symmetry and correlations induced by the Coulomb interaction. Comparison with shell model and Complex excited Vampir calculations.
