Analysis of Intermediate-Energy Nucleus-Nucleus Spallation, Fission, and Fragmentation Reactions with the LAQGSM code

TL;DR

This paper evaluates the LAQGSM code's ability to simulate nuclear reactions at intermediate energies, benchmarking it against experimental data and other models for proton and nucleus-nucleus interactions from 10 MeV to 800 GeV.

Contribution

It provides a comprehensive validation of the LAQGSM code against experimental data and compares its predictions with other models for various nuclear reactions at intermediate energies.

Findings

LAQGSM accurately reproduces neutron spectra and reaction yields.

The code performs well across a wide energy range from 10 MeV to 800 GeV.

Benchmarking shows LAQGSM's predictions are consistent with experimental measurements.

Abstract

The LAQGSM code has been recently developed at Los Alamos National Laboratory to simulate nuclear reactions for proton radiography applications. We have benchmarked our code against most available measured data both for proton-nucleus and nucleus-nucleus interactions at incident energies from 10 MeV to 800 GeV and have compared our results with predictions of other current models used by the nuclear community. Here, we present a brief description of our code and show illustrative results obtained with LAQGSM for neutron spectra measured recently by Nakamura's groups for reactions induced by light and medium nuclei on targets from C to Pb at several incident energies from 95 to 600 MeV/nucleon and with the recent GSI measurements of spallation, fission, and fragmentation yields from A+p and A+A reactions at incident energies near and below 1 GeV/nucleon. Further necessary work is outlined.
