Elastic and inelastic scattering of 16 MeV polarized deuterons by /sup 70,72,74/Ge

Cross section and vector analyzing power for the elastic and inelastic scattering of 16 MeV deuterons on /sup 70,72,74/Ge have been measured over the angular range 300 to 1450. In addition to the strongly excited 2+1 and 3- states, data have been obtained for the 0+2, 2+2, and 4+1 levels, as well as for several more highly excited levels in each isotope. The results have been compared with both distorted-wave Born-approximation and coupled-channels calculations, the latter employing both vibrational and rotational models. Although the coupled-channels analysis does not permit an unambiguous distinction between these two models on the basis of the data for the 0+1, 2+1, and 4+1 levels, the results are not inconsistent with a transition from oblate to prolate deformation between 72Ge and 74Ge. Spin and parity assignments are given for some of the states above 2 MeV of excitation
