Measurement of the g factors of isomers near the proposed N approximate to40 subshell closure

We report results from a pioneering experiment to measure the g factors of isomeric states of neutron-rich nuclei around Ni-68, far from the valley of beta stability. For the first time, the time-dependent perturbed angular d istribution method was applied in combination with the heavy-ion-gamma corr elation technique to study g factors of spin-aligned isomers produced in a projectile fragmentation reaction and mass-separated. Some technical aspect s are discussed and illustrated with preliminary results. (C) 2001 MAIK "Na uka/Interperiodica".
