$s$-wave scattering lengths for the ${}^7$Be+p system from an $\text{R}$-matrix analysis

S. N. Paneru, C. R. Brune, R. Giri +23

The astrophysical $S$-factor for the radiative proton capture reaction on ${}^7$Be ($S_{17}$) at low energies is affected by the $s$-wave scattering lengths. We report the measuremen…
