Lifetime measurements in neutron-rich ^{63, 65}Co isotopes using the AGATA demonstrator

NUCLEAR REACTIONS ²³⁸U(⁶⁴Ni, X)⁶³Co/⁶⁵Co, E=460 MeV; measured Eγ, Iγ, level half-lives by RDDS method using PRISMA magnetic spectrometer and AGATA array at LNL tandem-ALPI accelerator complex. ^63,65Co; deduced levels, B(E2), configuration. Systematics of B(E2) values for 11/2- to 7/2- transitions in ^63,65,67Co, and first 2+ to g.s. transitions in ^64,66Fe, ^64,66,68Ni. Calculated neutron occupation numbers for g_9/2 and d_5/2 orbitals for lowest 11/2- states in Co isotopes and first 2+ states in Ni and Fe isotopes. Shell-model calculations.
