Abstract

An investigation of some possible methods of calculating the heavy particle stripping amplitude in the distorted wave approximation is carried out. The validity of the zero-range approximation analogous to that used in ordinary stripping is examined and results indicate that its range of validity is very restricted. A less aproximate method is investigated involving a finite-range interaction and harmonic oscillator functions which yields a calculable result. Numerical calculations are presented for the reaction F¹⁹(d, p)F²⁰ and the various approximations compared. A comparison of the finite-range calculation with experiment indicates the need for a two-mode stripping theory for this reaction.

Absolute differential cross sections for the ¹¹B(p, α) reaction leading to the ground state of ⁸Be have been measured at E_p = 12, 20, 24 and 30 MeV. These results and previous results at E_p = 26.7 and 38 MeV have been compared with PWBA calculations taking into account direct mechanisms and their interference term. Two possibilities have been investigated: firstly, pick-up and heavy-particle pick-up, secondly, knock-out and heavy-particle pick-up. Both possibilities agree well with experimental results.
