Abstract :Using an iterative scheme, the effects of a more correct treatment of large n-p components of deuteron channel wavefunction in the continuum, which are associated with near-side contributions of transition amplitude, are investigated in the framework of the reformulated quasi-adiabatic model for the \( 116 \)Sn \( (d,p) \) \( 117 \)Sn reaction at 79 MeV bombarding energy. As the \( \elln \)-transfer rises, the far-side amplitude increases with improvements in the linear and angular momentum responce, which results in a relative suppression of the near-side components of the amplitude. Therefore, one might expect that the iteration of the quasi-adiabatic model calculations could provide significant improvements for the momentum mismatched reactions associated with low \( \elln \)-transitions at medium energies. However, the modifications brought by the iterative solution are analyzed quantitatively and shown not to be significant for both the angular momentum mismatched-volume dominated low \( \elln \)-transitions and well angular momentum matched-surface dominated large \( \elln \)-transitions, as there has been found no considerable effect on the angular distributions of the reaction observables in going from the zeroth order to the iterated calculations for the reaction of interest.Keywords : Turk.
