Abstract
We propose a novel approach to intranuclear cascades which takes as input quantum MonteCarlo nuclear configurations and uses a semi-classical, impact-parameter based algorithm to modelthe propagation of protons and neutrons in the nuclear medium. We successfully compare oursimulations to available proton-carbon scattering data and nuclear-transparency measurements. Byanalyzing the dependence of the simulated observables upon the ingredients entering our intranuclearcascade algorithm, we provide a quantitative understanding of their impact. Particular emphasisis devoted to the role played by nuclear correlations, the Pauli exclusion principle, and interactionprobability distributions.
Highlights
The propagation of nucleons through the nuclear medium is an important aspect of nuclear reactions, heavy-ion collisions, and astrophysical environments
We propose a novel cascade model that employs nuclear configurations obtained from quantum Monte Carlo (QMC) calculations, which retains all correlation effects
We implement a version of the nucleon-nucleon interaction algorithm that we dub mean-free path (MFP)
Summary
The propagation of nucleons through the nuclear medium is an important aspect of nuclear reactions, heavy-ion collisions, and astrophysical environments It is crucial in the analysis of electron-nucleus scattering experiments The seminal papers by Serber and Metropolis et al [20,21,22,23] laid the foundations for the use of Monte Carlo techniques in semiclassical intranuclear cascades (INC) that assume classical propagation between consecutive scatterings. The latter are modeled using free-space elementary cross sections whose final state is modified to account for the Pauli principle. The results obtained by these first implementations of INC agree at least
