Nucleon knockout reactions have been used to extract single particle information from nuclei. The analysis of nucleon knockout from a stable projectile in the collision with a proton target and the comparison with the experimental data is a key test for the reaction and structure models used to evaluate the reaction observables.
Three-body Faddeev/Alt-Grassberger-Sandhas (Faddeev/AGS) equations for transition operators [1,2] have been solved for p- and n-knockout from 12C at 400 Mev/u, assuming that only the heavy fragment or core C (taken as inert), the knockout particle N, and the proton target p participate in the collision process [3].
We present calculated kinematically fully exclusive, semi-inclusive and inclusive cross sections and an analysis of the
(i) dominant kinematic conditions of the emitted particles;
(ii) isospin dependence (here p- and n- knockout) of the calculated reaction cross sections.
(iii) Final state interaction (FSI) to the calculated observables
A comparison with available data [4] is shown. Future developments are discussed.
