Abstract
Transition probabilities from lifetimes of excited states in neutron-rich nuclei 52;54Ti, produced in a multinucleon-transfer reaction, were measured employing the recoil distance Doppler-shift (RDDS) method. The experiment was performed at the Grand Accélérateur National d’Ions Lourds (GANIL) facility by using the Advanced Gamma Tracking Array (AGATA) for the γ- ray detection and the Cologne plunger device for deep inelastic reactions, coupled to the large-acceptance variable mode spectrometer (VAMOS++) for an event-by-event particle identification. The aim was the investigation of the evolution of the shell structure in the vicinity of the N = 32 subshell. Level lifetimes and lifetime limits of the 2+1 to 8+1 states of the yrast bands in 52;54Ti are determined. The obtained transition probabilities are compared to shell-model calculations based on established fp shell interactions.
