Polarized proton+$^{4,6,8}$He elastic scattering with breakup effects in the eikonal approximation

TL;DR

This paper investigates polarized proton scattering on helium isotopes using Glauber theory, accounting for breakup effects, and compares results with experimental data at 71 MeV, also predicting observables at 300 MeV.

Contribution

It introduces a method to include breakup effects in optical potentials for proton-helium scattering within the eikonal approximation.

Findings

Differential cross sections agree with experimental data at 71 MeV.

Vector analyzing powers are well reproduced at 71 MeV.

Predictions for scattering observables at 300 MeV are provided.

Abstract

We study the elastic scattering of polarized protons from He isotopes. The central and spin-orbit parts of the optical potential are derived using the Glauber theory that can naturally take account of the breakup effect of the He isotopes. Both the differential cross section and the vector analyzing power for $p+^{4,6,8}$He scattering at 71 MeV are in reasonable agreement with experiment. Scattering observables at 300 MeV are predicted. The Pauli blocking effect is examined at 71 MeV.
