Abstract

We point out a simple relation between the nuclear vertex constant (NVC) and the overall normalization of the astrophysical $S$ factor. Using predicted values of the NVC for the virtual decay of $^{8}\mathrm{B}\ensuremath{\rightarrow}^{7}\mathrm{Be}+p$ we find ${S}_{17}(0)\ensuremath{\approx}17.6$ e...
