# Additive empirical parametrization and microscopic study of the deuteron breakup

## TL;DR

This study compares empirical and microscopic models of deuteron breakup cross sections across various energies and targets, highlighting their similarities and discrepancies to guide future experimental and theoretical work.

## Contribution

It introduces an additive empirical parametrization and assesses microscopic calculations against experimental data for deuteron breakup cross sections.

## Key findings

- Comparable mass dependences of EB cross sections from both models.
- Variance in absolute values up to a factor of two due to limited high-energy data.
- Validation of microscopic calculations through observed similarities.

## Abstract

Comparative assessment of the total breakup proton-emission cross sections measured for 56 MeV deuteron interaction with target nuclei from $^{12}$C to $^{209}$Bi, with an empirical parametrization and recently calculated microscopic neutron-removal cross sections has been done at the same time with similar data measured at 15, 25.5, 70, and 80 MeV. Comparable mass dependances of the elastic-breakup (EB) cross sections provided by the empirical parametrization and the microscopic results have been also found at the deuteron energy of 56 MeV, while the assessment of absolute-values variance up to a factor of two has been not possible due to the lack of EB measurements at energies higher than 25.5 MeV. While the similarities represent an additional validation of the microscopic calculations, the cross-section difference should be considered within the objectives of further measurements.
