Lifetime measurements in neutron-rich Fe and Co isotopes

Lifetimes of yrast states in neutron-rich Fe and Co isotopes were measured using the differential Recoil Distance Doppler Shift (RDDS) and the differential decay curves methods. The nuclei of interest were populated in multi-nucleon transfer in inverse kinematics. The deduced B(E2) values are compared with large-scale shell-model calculations, leading to a better understanding of the mechanisms at the origin of the onset of collectivity in the region just below 68Ni

Lifetime measurement of 2(1)(+) state in zn-74 with differential plunger technique

We have measured the lifetime of the 2(1)(+) state in Zn-74 by the recoil distance Doppler-shift method at GANIL. It resulted to be of 27.6(43) ps and is consistent with previously measured values of transition rates from Coulomb excitation measurements
