Scattering of deuterons by nuclei with breakup effects

Abstract

The deuteron direct-breakup reaction is explicitly incorporated into the d + nucleus formulation of model K which is a simplified version of the microscopic resonating-group method. By employing the same nucleon-nucleon potential as that used in the corresponding nucleon + nucleus system and by adopting an imaginary potential with a single adjustable parameter to crudely represent other reactions not explicitly included in the formulation, it is shown that a good agreement between calculated and experimental differential cross sections can be obtained for deuteron scattering by a wide variety of target nuclei, ranging from 28Si to 208Pb. In addition, the results also indicate that the deuteron breakup reaction is a significant, but not dominant, reaction in the d + nucleus system. To make model K into a truly microscopic model without any phenomenological imaginary potential, one must further explicitly include the (d, p) and (d, n) one-nucleon-transfer or stripping reactions into the model-K formulation.
