Role of direct interactions in (d, p) and (d, 2p) reactions

Abstract

Accurate cross sections of deuteron–induced reactions within an enlarged energy range up to 50 MeV are definitely involved by demands of on-going strategic research programs (ITER, IFMIF, SPIRAL2-NFS) using deuteron beams. Among them, the (d, p) and (d, 2p) reaction cross sections leading to hydrogen– gas bubble accumulation in the structural materials are very important for radiation damage studies. In contrast to the case of neutrons, systematics of deuteron activation cross sections, including those leading to hydrogen, triton, and helium–gas accumulation, is modest while even the newest evaluations show apparent discrepancies. Thus, the present work is devoted to the comparative analysis of measurements, model calculations, and evaluation corresponding to (d, p), and (d, 2p) activation cross sections, to improve the description of existing data and to provide trustful predictions where no measured data exist.
