Abstract

The g factor of the 21+ state in Ge70 was remeasured using a different experimental approach. Furthermore, for the first time an experimental value (although with a large uncertainty) was obtained for the g factor of the 22+ state in Ge70. All this was accomplished by employing the technique of α transfer to an energetic Zn66 ion beam in inverse kinematics combined with transient magnetic fields in ferromagnetic gadolinium. The value of the g(21+) factor obtained ranges from +0.32(11) to +0.43(12), subject to certain assumptions. This range of values is in general agreement with the range of values in the literature, where Coulomb excitation and different IMPAC techniques were used. Lifetimes of several low-lying states were redetermined using the Doppler-Shift-Attenuation-Method. The deduced B(E2) values and the g(21+) factor are discussed within the framework of large-scale full fp shell model calculations with a closed Ca40 core and including excitations from the f7/2 orbital. The results are compared with recent data for Ge68 and Zn68.
