Capture cross sections of 15N(n, {\gamma})16N at astrophysical energies

TL;DR

This study reanalyzed 16N reaction cross sections on 12C, extracting surface nucleon densities with a modified Glauber model, and used these to model the 15N(n,γ)16N reaction via direct capture, matching experimental data.

Contribution

It introduces a method to extract surface nucleon densities of 16N and applies this to model the 15N(n,γ)16N reaction mechanism.

Findings

Calculated cross sections agree well with experimental data.

Surface density distributions of 16N were successfully extracted.

The direct capture model effectively describes the reaction at astrophysical energies.

Abstract

We have reanalyzed reaction cross sections of 16N on 12C target. The nucleon density distribution of 16N, especially surface density distribution, was extracted using the modified Glauber model. On the basis of dilute surface densities, the discussion of 15N(n, {\gamma})16N reaction was performed within the framework of the direct capture reaction mechanism. The calculations agreed quite well with the experimental data.
