摘要

The impact of the core and the projectile excitations on the nuclear breakup reaction 9Be(28P, 27Si)X at an incident beam energy of 65 MeV/nucleon has been investigated. This analysis considers both stripping and diffraction dissociation mechanisms using the standard MOMDIS code, which is based on the Glauber eikonal formalism. To calculate the breakup observables – specifically, the longitudinal momentum distribution (LMD) of the core fragment and the single-proton breakup cross-section – we incorporated the ground and low-lying bound excited states of both the core and the projectile. Additionally, the contribution of individual s and d-states in forming the sd-admixed state was explored using the LMD width as a diagnostic tool. The results demonstrate that the inclusion of the core and the projectile excitations is crucial to the breakup reaction of 28P. We anticipate that this study will contribute to understanding the structure of the projectile 28P.
