$S$-factor and scattering-parameter extractions from ${}^3\mathrm{He}+{}^4\mathrm{He}\to {}^7\mathrm{Be}+\gamma$

Xilin Zhang, Kenneth M. Nollett, D. R. Phillips

Previous studies of the reaction ${}^3\mathrm{He}+{}^4\mathrm{He}\to {}^7\mathrm{Be}+\gamma$ have focused on providing the best central value and error bar for the $S$…
