Title: Nuclear structure investigations of the Ge isotopes by means of (p,t) reactions and microscopic studies of nuclear deformations and collective spectra

Journal Article · · Phys. Rev., C; (United States)

Systematics are presented from our study of the Ge nuclei by means of the (p,t) reaction. From observed intensities and excitation energies, conclusions are drawn concerning structure and reaction mechanisms. They are discussed in the frame of microscopic calculations. These calculations predict a shape transition from a nearly spherical nucleus (/sup 70/Ge) to a slightly oblate one (/sup 74/Ge). The energies of the low-lying 0/sup +/ levels are well fitted; dynamical effects induced by pairing fluctuations are shown to play a major role in this feature as well as in the striking evolution of their intensities in the (p,t) reaction. A connection is presented with the possibility of 0/sup +/ pairing isomer states. The outstanding splitting of the L = 3 strength at N = 42 appears as a characteristic feature of this region suggesting coupling effects in octupole modes.
