Ground State Transition of (p,t) Reactions on Ni Isotopes

Abstract

Angular distributions of 68,60i62,64Ni(p,t) ground state transitions at Ep = 25MeV have been measured and compared with distorted wave Born approximation predictions. Relative enhancement factors for four Ni isotopes have been extracted. Comparison between the enhancement factors and the predictions of interacting boson approximation model has been made. It is found that a value of R, = 6 is needed to describe the experimental result in SU(5) calculation.
