TL;DR

This paper investigates the formation of the $^{5}{ m Li}$ nucleus during proton-$ mf extalpha$ scattering at energies up to 20 MeV using a bremsstrahlung model that links photon emission to compound nucleus formation.

Contribution

It introduces a novel bremsstrahlung model incorporating microscopic theory elements to analyze compound nucleus formation probabilities from experimental photon emission data.

Findings

Calculated bremsstrahlung spectra agree well with experimental data.

The model provides insights into the probabilities of short-lived compound nucleus formation.

The approach enhances understanding of many-nucleon dynamics in nuclear reactions.

Abstract

In this paper a role of many-nucleon dynamics in formation of the compound $^{5}{\rm Li}$ nucleus in the scattering of protons off $\alpha$-particles at the proton incident energies up to 20 MeV is investigated. We propose a bremsstrahlung model allowing to extract information about probabilities of formation of such nucleus on the basis of analysis of experimental cross-sections of the bremsstrahlung photons. In order to realize this approach, the model includes elements of microscopic theory and also probabilities of formation of the short-lived compound nucleus. Results of calculations of the bremsstrahlung spectra are in good agreement with the experimental cross-sections.
