Shape evolution in self-conjugate nuclei, and the transitional nucleus ⁶⁸Se

NUCLEAR REACTIONS ¹⁹⁷Au(⁶⁸Se, X), E=92 MeV/nucleon; measured Eγ, Iγ, (particle)γ-coin, t-o-f method using SeGa array. ⁶⁸Se, ⁷⁸Kr; deduced levels, J, π, B(E2). Coulomb excitation. Systematics of first 2+ states in Z=30-38 self-conjugate nuclei. Comparisons with several theoretical predictions.

NUCLEAR STRUCTURE ⁶⁰Zn, ⁶⁴Ge, ⁶⁸Se, ⁷²Kr, ⁷⁶Sr; calculated probability density for the collective wave functions of first 2+ states in the β-γ triaxial plane through a parameter-free beyond-mean-field approach using the Gogny D1S interaction within a GCM+GOA formalism.
