TL;DR

This paper investigates relativistic effects on the breakup of weakly-bound nuclei at intermediate energies using a continuum-discretized coupled-channels method with eikonal approximation, highlighting the impact of Lorentz contraction on cross sections.

Contribution

It introduces nuclear coupling potentials with Lorentz contraction into the continuum-discretized coupled-channels framework for the first time.

Findings

Relativistic corrections increase breakup cross sections.

Lorentz contraction significantly affects nuclear coupling potentials.

Coupled-channel effects are important in accurately modeling breakup processes.

Abstract

Relativistic effects in the breakup of weakly-bound nuclei at intermediate energies are studied by means of the continuum-discretized coupled-channels method with eikonal approximation. Nuclear coupling potentials with Lorentz contraction are newly included and those effects on breakup cross sections are investigated. We show that relativistic corrections lead to larger breakup cross sections. Coupled-channel effects on the breakup cross sections are also discussed.
