Establishing a theory for deuteron induced surrogate reactions

TL;DR

This paper develops a comprehensive theoretical framework for deuteron-induced neutron capture reactions, including elastic and inelastic breakup, validated against experimental data for 53Nb at specific energies.

Contribution

It introduces a consistent formulation of breakup processes in both post and prior distorted wave Born approximation, connecting to neutron transfer reactions.

Findings

Good agreement with experimental data for 53Nb(d,p)X at 15 and 25 MeV

Analysis of partial wave contributions and elastic vs inelastic breakup

Framework links breakup theory with neutron transfer to bound states

Abstract

The goal of this work is to establish on firm grounds a theory for deuteron induced neutron capture reactions. This includes formulating elastic and inelastic breakup in a consistent manner. We describe this process both in post and prior form distorted wave Born approximation, and we apply our method to the 53Nb(d,p)X at Ed =15 MeV and 25 MeV, obtaining a good description of the data. We look at the various partial wave contributions, as well as elastic versus inelastic contributions. We also connect our formulation with transfer to neutron bound states.
