Proton Spectroscopic Factor in 7Li from 2H(6He,7Li)n

TL;DR

This study measured the angular distribution of the 2H(6He,7Li)n reaction at 36.4 MeV to extract the proton spectroscopic factor of 7Li, providing insights into nuclear structure and reaction mechanisms.

Contribution

First measurement of the angular distribution for this reaction at this energy, and extraction of the proton spectroscopic factor using DWBA analysis.

Findings

Proton spectroscopic factor of 7Li ground state is 0.41 ± 0.05.

Uncertainty in spectroscopic factors can be reduced by constraining optical potential volume integrals.

First experimental data for this specific reaction at this energy.

Abstract

The angular distribution of the 2H(6He,7Li)n reaction was measured with a secondary 6He beam of 36.4 MeV for the first time. The proton spectroscopic factor of 7Li ground state was extracted to be 0.41 +- 0.05 by the normalization of the calculational differential cross sections with the distorted-wave Born approximation to the experimental data. It was found that the uncertainty of extracted spectroscopic factors from the one-nucleon transfer reactions induced by deuteron may be reduced by constraining the volume integrals of imaginary optical potentials.
