Multiple scattering effects in quasi free scattering from halo nuclei: a test to Distorted Wave Impulse Approximation

TL;DR

This paper investigates multiple scattering effects in quasi-free scattering from halo nuclei using full Faddeev calculations and compares them with the Distorted Wave Impulse Approximation to evaluate the latter's accuracy.

Contribution

It provides a detailed comparison between full Faddeev calculations and the truncated DWIA, highlighting the importance of multiple scattering effects in halo nuclei breakup.

Findings

Faddeev calculations show convergence of multiple scattering expansion.

DWIA results differ significantly from Faddeev calculations at certain energies.

Multiple scattering effects are crucial for accurate modeling of halo nuclei breakup.

Abstract

Full Faddeev-type calculations are performed for $^{11}$Be breakup on proton target at 38.4, 100, and 200 MeV/u incident energies. The convergence of the multiple scattering expansion is investigated. The results are compared with those of other frameworks like Distorted Wave Impulse Approximation that are based on an incomplete and truncated multiple scattering expansion.
