Collective modes of excitation in ⁶⁴Cu

NUCLEAR REACTIONS ²⁶Mg(⁴⁸Ca, 5npα)⁶⁴Cu, E=275, 290, 320 MeV; measured Eγ Iγ, γγγ-coin, γγ()θ, (particle)γ-coin. ⁶⁴Cu; deduced levels, J, π, δ angular correlation ratios, angular distribution coefficients, high-spin states, transitions quadrupole moments, bands structure, rotational bands; calculated potential energy surface in β-γ plane, single-proton and single-neutron levels, B(E2). Analysis with the help of calculations carried out within the framework of the adiabatic and configuration-fixed constrained covariant density functional theory and the quantum particle-rotor model. Systematics of deformed and superdeformed bands in ⁶⁴Zn, ⁶⁸Zn, ⁵⁹Cu, ⁵⁸Cu. GAMMASPHERE array of of 101 Compton-suppressed HPGe and the fragment mass analyzer (FMA) at the ATLAS accelerator facility (Argonne National Laboratory).
