Fission induced by nucleons at intermediate energies

TL;DR

This paper uses Monte Carlo simulations with the INCL++ model and evaporation-fission codes to study nucleon-induced fission of actinides at intermediate energies, aiming to predict cross sections accurately.

Contribution

It introduces a combined modeling approach using INCL++ with GEMINI++ and ABLA07 to simulate fission induced by protons and neutrons at energies from 100 MeV to 1 GeV.

Findings

Model parameters adjusted to (p,f) data improve (n,f) predictions.

Simulation results align with experimental fission cross sections.

The approach enhances understanding of nucleon-induced fission at intermediate energies.

Abstract

Monte Carlo calculations of fission of actinides and pre-actinides induced by protons and neutrons in the energy range from 100 MeV to 1 GeV are carried out by means of a recent version of the Li\`ege Intranuclear Cascade Model, INCL++, coupled with two different evaporation-fission codes, GEMINI++ and ABLA07. In order to reproduce experimental fission cross sections, model parameters are usually adjusted on available (p,f) cross sections and used to predict (n,f) cross sections for the same isotopes.
