Artículo Binding-energy independence of reduced spectroscopic strengths derived from (p, 2p) and (p, pn) reactions with nitrogen and oxygen isotopes(ELSEVIER, 2018-08-30) Gómez Ramos, Mario; Moro Muñoz, Antonio Matías; Universidad de Sevilla. Departamento de Física Atómica, Molecular y NuclearA campaign of intermediate energy (300–450 MeV/u) proton-induced nucleon knockout measurements in inverse kinematics has been recently undertaken at the R 3 B/LAND setup at GSI. We present a systematic theoretical analysis of these data with the aim of studying the quenching of the single-particle strengths and its binding-energy dependence. For that, the measured semi-inclusive (p, 2p) and (p, pn) cross sections are compared with theoretical predictions based on single-particle cross sections derived from a novel coupled-channels formalism and shell-model spectroscopic factors. A systematic reduction of about 20–30% is found, with a very limited dependence on proton–neutron asymmetry.
