Preliminary results of lifetime measurements in neutron-rich Ti-53

To study the nuclear structure of neutron-rich titanium isotopes, a lifetime measurement was performed at the Grand Accelerateur National d'Ions Lourds (GANIL) facility in Caen, France. The nuclei were produced in a multinucleon-transfer reaction by using a 6.76 MeV/u U-238 beam. The Advanced Gamma Tracking Array (AGATA) was employed for the gamma-ray detection and target-like recoils were identified event-by-event by the large-acceptance variable mode spectrometer (VAMOS++). Preliminary level lifetimes of the (5/2(-)) to 13/2(-) states of the yrast band in the neutron-rich nucleus Ti-53 were measured for the first time employing the recoil distance Doppler-shift (RDDS) method and the compact plunger for deep inelastic reactions. The differential decay curve method (DDCM) was used to obtain the lifetimes from the RDDS data.
