Comment on "Sensitivity of ($d,p$) Reactions to High $n$-$p$ Momenta and the Consequences for Nuclear Spectroscopy Studies"

TL;DR

This paper critiques the sensitivity of ADWA with NLOP in $(d,p)$ reactions, highlighting that more rigorous Faddeev calculations do not show this sensitivity, and discusses limitations of the ADWA approach.

Contribution

It provides a critical analysis of ADWA with NLOP, contrasting it with Faddeev results, and identifies shortcomings in the ADWA method for $(d,p)$ reactions.

Findings

Faddeev calculations show no sensitivity to $n$-$p$ force models.

ADWA with NLOP has limitations and can be misleading.

The sensitivity observed in previous work is not supported by rigorous methods.

Abstract

Using adiabatic distorted-wave approximation (ADWA) with nonlocal optical potentials (NLOP) for $(d,p)$ transfer reactions [G.W. Bailey, N.K. Timofeyuk, and J.A. Tostevin, Phys. Rev. Lett. 117, 162502 (2016)] reported strong sensitivity to the $n$-$p$ force model. This sensitivity disappears in rigorous three-body Faddeev-type results. Some shortcomings of ADWA with NLOP are pointed out.
