Core destruction in knockout reactions

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 with 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.(c) 2023 The Author(s). Published by Elsevier B.V.

Automated summary

A model is proposed to calculate projectile core destruction in knockout reactions. Secondary collisions between incoming and struck nucleons are found to decrease the core survival probability, but there is no clear evidence for a reduction in cross section with increasing binding energy of the removed nucleon.
