Magnetic moments and B(E2) values are sensitive probes for determining the nuclear structure. This has been demonstrated by several recent measurements using the new technique of projectile Coulomb excitation in inverse kinematics combined with transient magnetic fields [1]. The high quality of the experimental data even allowed to test effective NN-interactions used in shell model calculations. New precise measurements were performed for the 21+ states of 64−70Zn isotopes and, for the first time, for radioactive 62Zn. Isotopically pure Zn beams with energies of 160 MeV, provided by the tandem accelerator at Munich, were Coulomb excited with a natural carbon target. The 62Zn(21+) state was strongly populated in the α-transfer reaction from 12C to 58Ni beams of 155 MeV. The results are compared with large scale shell model calculations.
