This paper demonstrates the feasibility of quadrupole moment measurements on isomeric levels populated in projectile fragmentation reactions. The neutron-rich Fe-61(9/2(+)) [E-*= 861 keV, T-1/2= 239(5) ns] isomer was produced and spin aligned by the intermediate energy fragmentation of a Ni-64 beam and implanted in a Cd single crystal. Its spectroscopic quadrupole moment Q(s)=41(6) e fm(2) agrees with mean-field based calculations using the finite-range Gogny force, suggesting a moderately deformed shape characterized by an intrinsic charge quadrupole moment Q(0)=-85 e fm(2) or Q(0)=+115 e fm(2). The present measurement paves the way for future determinations of isomeric quadrupole moments in more exotic nuclei. ispartof: Physical Review C, Nuclear physics vol:75 issue:5 pages:1-4 status: published |
