Abstract

The (O16, N15) and (C12, B11) reactions on Ni62 target have been investigated with 56 MeV O16 and 48 MeV C12 beams. Angular distributions for transitions to the first five single particle states of Cu63 were obtained. An exact finite-range distorted-wave Born approximation analysis was performed, showing that the spectroscopic factors extracted agree fairly well with those obtained from light ion induced reactions. The role of multistep processes has also been investigated by performing exact finite-range coupled-channel Born approximation calculations which take into account the core excitation of the projectile or the target nucleus. It is found that in the case of the Ni62(C12, B11)Cu63 reaction both the intensity and shape of the angular distributions are affected by including the multistep contributions due to projectile excitation. In particular, the behavior of the angular distributions at small angles is better described by the coupled-channel Born approximation calculations. The indirect routes involving the inelastic excitations of the O16 or Ni62 nuclei are shown to be unimportant.
