Abstract: The mechanism of deuteron formation in neutron-induced reactions is studied within the framework of the isospin-dependent quantum molecular dynamics (IQMD) model, using the GEMINI code. The influence of the n+p!d reaction channel is investigated by analyzing the deuteron production cross-sections in the neutroninduced reactions 12C(n,d), 16O(n,d), and 28Si(n,d), with incident energies of 20-100 MeV. By including the n+p!d reaction channel when modeling the collision, the deuteron production cross-sections increase, optimizing the cross-section results and bringing them closer to the experimental data values. This indicates that the n+p!d reaction channel is an important mechanism for enhancing deuteron production.
