Inclusive deuteron-induced reactions and final neutron states

TL;DR

This paper develops a formalism for inclusive deuteron-induced reactions, separating elastic breakup from other processes, and modeling the neutron-target system as a two-step process involving breakup and propagation.

Contribution

It introduces a new formalism that distinguishes different reaction mechanisms and models the neutron-target interaction using an optical potential framework.

Findings

Formalism effectively separates elastic and non-elastic breakup contributions.

Reaction modeled as a two-step process involving breakup and neutron propagation.

Framework includes the formation of excited compound nuclei.

Abstract

We present in this paper a formalism for deuteron-induced inclusive reactions. We disentangle direct elastic breakup contributions from other processes (which we generically call non-elastic breakup) implying a capture of the neutron both above and below the neutron emission threshold. The reaction is described as a two step process, namely the breakup of the deuteron followed by the propagation of the neutron-target system driven by an optical potential. The final state interaction between the neutron and the target can eventually form an excited compound nucleus. Within this context, the direct neutron transfer to a sharp bound state is a limiting case of the present formalism.
