Proton-Induced Fission and Spallation Reactions in Inverse KinematicsInsights from CALIFA Calorimeter Reconstruction

Resumen

This thesis work focuses on investigating proton-induced reactions on ²³⁸U in inverse kinematics, taking advantage of the R³B/ SOFIA setup. Nuclear fission was induced after knockout processes, with scattered nucleons being analyzed using the CALIFA calorimeter. Innovative reconstruction algorithms were developed for CALIFA to extract the process's excitation energy through an invariant mass approach which was then correlated with fragment charge yields and compared with theoretical models across various physics model configurations. Furthermore,cross-sections for spallationfission and spallation-evaporation channels were measured. The obtained data demonstrate good agreement with previous measurements and theoretical calculations.
