The normalization constant has been calculated for the Ni-62(He-3, p)Cu-64
reaction leading to the ground-state analogue (0(+); 4) at E-x = 6.82 MeV a
nd the excited-state analogue (2(+); 4) at E-x = 8.19 MeV in Cu-64, from a
comparison of the angular distribution of cross-section data with DWBA pred
ictions. The normalization constants extracted from the data for these two
analogue states are found to vary by an order of magnitude. One reason for
this variation may be the influence of processes other than the simple one-
step mechanism. CCBA calculations for the core excitation of Ni-62, and CRC
calculations for sequential transfer via the (He-3-d-p) path have been car
ried out for the reaction leading to the 6.82 MeV(0(+); 4) state in order t
o investigate the importance of alternative reaction mechanisms and to just
ify the reliability of the deduced normalization constant for the ground-st
ate analogue transition.
