Core destruction in knockout reactions

TL;DR

This paper introduces a model to calculate projectile core destruction in knockout reactions, accounting for secondary collisions and their impact on core survival probability at energies around 100 MeV/nucleon.

Contribution

It presents a new model that incorporates physics-based arguments to estimate core destruction, including secondary collision effects, in heavy ion knockout reactions.

Findings

Secondary collisions reduce core survival probability by up to 9.5%

No clear correlation between binding energy and cross section reduction

Abstract

A model is presented to calculate projectile core destruction in knockout reactions. It incorporates physics arguments similar to the formulation of the state of the art theory to calculate stripping and diffraction dissociation cross sections in heavy ion collisions with bombarding energies around 100 MeV/nucleon and larger. It is shown that secondary collisions between the incoming and struck nucleons and the projectile core decrease the core survival probability by as much as 9.5\%. However, no clear evidence is found for reduction of the cross section with increasing binding energy of the removed nucleon.
