Abstract
This paper demonstrates the feasibility of quadrupole moment measurements on isomeric levels populated in projectile fragmentation reactions. The neutron-rich [ 861 keV, 239(5) ns] isomer was produced and spin aligned by the intermediate energy fragmentation of a beam and implanted in a Cd single crystal. Its spectroscopic quadrupole moment agrees with mean-field based calculations using the finite-range Gogny force, suggesting a moderately deformed shape characterized by an intrinsic charge quadrupole moment or . The present measurement paves the way for future determinations of isomeric quadrupole moments in more exotic nuclei.
