Asymptotic normalization coefficients for ${\rm {^7Be}}+p\to{\rm{^8B}}$ from the peripheral ${\rm{^7Be}}$($d$,$n$)${\rm{^8B}}$ reaction and their astrophysical application

TL;DR

This study analyzes the ${^7Be}(d,n){^8B}$ reaction at 4.5 MeV using modified DWBA to estimate asymptotic normalization coefficients, the astrophysical $S_{17}(0)$ factor, and scattering lengths, aiding nuclear astrophysics models.

Contribution

It provides new estimates for asymptotic normalization coefficients and related astrophysical parameters using a modified DWBA analysis of the ${^7Be}(d,n){^8B}$ reaction.

Findings

New values for asymptotic normalization coefficients with uncertainties.

Updated estimates of the astrophysical $S_{17}(0)$ factor.

Refined s-wave $p + {^7Be}$ scattering lengths.

Abstract

The proton transfer ${\rm{^7Be}}$($d$,$n$)${\rm{^8B}}$ reaction at the energy of 4.5 MeV (c.m.) has been analysed within the modified DWBA. New estimates and their uncertainties are obtained for values of the asymptotic normalization coefficients for $p + {\rm{^7Be}} \to {\rm{^8B}}$, the astrophysical $S_{17}(0)$ factor and the s-wave $p + {\rm{^7Be}}$ scattering lengths.
