Inelastic Processes in Particle Transfer Reactions

Abstract

There are certainly some levels in all nuclei, and all levels in some nuclei for which the usual treatment of particle transfer reactions, which neglects inelastic effects, is invalid. Here a practical method for taking these effects into account is described. The method is discussed in terms of the (d,p) reaction, but i t has a much broader application than this .

Reexamining closed-form formulae for inclusive breakup: Application to deuteron- andLi6-induced reactions

“…(12) is formally analogous to the inhomogeneous equation appearing in DWBA and coupled-channel Born approximation (CCBA) calculations between bound states, as formulated in the source term method of Ascuitto and Glendenning [33] and used by several coupled-channels codes [34].…”

The importance of indirect transitions on (p, t) reactions on deformed nuclei

“…It has been known for some time that the excitation of intermediate states in inelastic scattering is important for deformed nuclei, though not so important for vibrational nuclei, except for any state whose structure forbids' or inhibits its direct production in a single interaction (such as 2-phonon states). In the last several years we have been investigating the question of whether higher order processes in nucleon transfer reactions [1][2][3][4][5][6][7][8] are important…”

The theoretical analysis of nuclear reactions involving strongly deformed nuclei using phenomological models

“…Similarly, the deuteron wavefunc~ions can be written (4) where. S.p · and $" are the spinors for the proton and neutron respectively, and we have written th~ deuteron wavefunction…”
