Empirical Evaluation of Gamow-Teller Strength Function for Cl-37 --> Ar-37 and its Implication in the Cross Section for Solar Neutrino Absorption by Cl-37

TLDR: In this paper, the Gamow-Teller strength for neutrino absorption in the angular range of 0, 30, √ √ ifmmode^ √circ\circ\else\text degree\fi{} was obtained.

Abstract: Neutron spectra from $^{37}\mathrm{Cl}$($p$,$n$)$^{37}\mathrm{Ar}$ at ${E}_{p}=120$ MeV are measured in the angular range 0\ifmmode^\circ\else\textdegree\fi{}-30\ifmmode^\circ\else\textdegree\fi{}. Neutron groups characterized with $L=0$ transfer are obtained up to approximately 12-MeV excitation energy in $^{37}\mathrm{Ar}$. From the observed 0\ifmmode^\circ\else\textdegree\fi{} cross section the Gamow-Teller strengths for $^{37}\mathrm{Cl}$\ensuremath{\rightarrow}$^{37}\mathrm{Ar}$ transitions are obtained which are directly related to neutrino absorption by $^{37}\mathrm{Cl}$. The cross section for $^{8}\mathrm{B}$ solar neutrinos incident on $^{37}\mathrm{Cl}$ is reported.
