Contribution to the study of deformed heavy nuclei by means of nuclear reactions

The experimental results obtained in the study of the (d,p) reactions, at Ed = 12 MeV, on the three even-even deformed nuclei 170Yb, 172Yb and 174Yb have been analysed in terms of DWBA calculations. The spectroscopic information relative to the odd final nuclei have been compared with the predictions of the collective model and of the Nilsson's model. The effect of various parameters used in the DWBA analysis (form factors, optical wave functions) has been carefully studied. The observed differences between the three final nuclei are qualitatively reproduced in the experimental study of resonances, seen in excitation functions of elastically and inelastically scattered protons on the same target nuclei, and corresponding to analogue states in the three nuclei 171Lu, 173Lu and 175Lu.
