Muon capture on Chlorine-35

Abstract

We report measurements of $\gamma$--ray spectra from muon capture on ${}^{35}$Cl. For the allowed Gamow--Teller transitions to the ${}^{35}$S$(2939,3/2^{+})$ state and the ${}^{35}$S$(3421,5/2^{+})$ state we obtained their capture rates, hyperfine dependences and $\gamma$--$\nu$ correlation coefficients. The capture rates and hyperfine dependences were compared to shell model calculations using the complete 1s--0d space and the universal SD interaction. With $g_p/g_a=6.7$ and $g_a=-1.00$ (or $g_a=-1.26$) we found agreement of the model and the data at the 1--2 $\sigma$ level. However, we caution that the transitions are sensitive to $\ell =2$ forbidden matrix elements.
