Two-nucleon correlation effects in knockout reactions from 12C

Nuclear Theory 2015-03-17 v2

Abstract

Reactions that involve the direct and sudden removal of a pair of like or unlike nucleons from a fast projectile beam by a light target nucleus are considered. Specifically, we study the three two-nucleon removal channels from 12^{12}{C} that populate final states in the 10^{10}{Be}, 10^{10}{B} and 10^{10}{C} reaction residues. The calculated two-nucleon removal cross sections and the residue momentum distributions are compared with available high energy data at 250, 1050 and 2010 MeV per nucleon, data that are inclusive with respect to the bound final-states of the residues. The measured npnp-removal cross sections only are significantly greater than the values calculated, suggesting that the reaction mechanism observes enhanced npnp spatial correlations compared to those present in the shell-model wave functions.
