Dynamical Relativistic Effects in Breakup Processes of Halo Nuclei

TL;DR

This paper investigates how relativistic effects, especially Lorentz contraction, influence the breakup processes of halo nuclei at intermediate energies using advanced computational methods.

Contribution

It introduces the application of the Eikonal CDCC method to account for relativistic effects in nuclear breakup reactions, highlighting the significance of Lorentz contraction on cross sections.

Findings

Lorentz contraction significantly increases breakup cross sections.

Close field contributions are negligible for loosely-bound nuclei.

The study enhances understanding of relativistic effects in nuclear reactions.

Abstract

The continuum-discretized coupled-channels (CDCC) method is used to study the breakup of weakly-bound nuclei at intermediate energies collisions. For large impact parameters, the Eikonal CDCC (E-CDCC) method was applied. The effects of Lorentz contraction on the nuclear and Coulomb potentials have been investigated in details. Such effects tend to increase cross sections appreciably. We also show that, for loosely-bound nuclei, the contribution of the so-called close field is small and can be neglected.
