Lifetime measurement in the region of neutron rich zirconium isotopes

A gamma-ray spectroscopy experiment for the measurement of excited states lifetimes of ¹⁰⁶Zr was performed at GSI using the PreSPEC-AGATA setup. A ²³⁸U primary beam from the SIS18 was fissioned on a Beryllium target positioned at the entrance of the FRagement Separator (FRS) to produce ¹⁰⁷Nb ions identified, and selected by the FRS. The particles of this secondary beam were fragmented at relativistic energy (β = v/c ∝ 0.5) on a 700 mg/cm² thick Beryllium target positioned at the center of the Advanced GAmma Tracking Array (AGATA). The ¹⁰⁶Zr reaction products were identified by the Lund York Cologne Calorimeter (LYCCA). The energy and position of the gamma-rays emitted by these ejectiles were measured by 19-AGATA detectors. The position sensitivity of AGATA coupled with LYCCA detectors allow a lifetime determination using the Doppler Shift Attenuation Method (DSAM). The status of the data analysis and preliminary lifetime estimations are presented.
