Muon capture on Chlorine-35

We report measurements of $\gamma$–ray spectra from muon capture on ${}^{35}$Cl. For the allowed Gamow–Teller transitions to the ${}^{35}$S$(2939, 3/2^+)$stateandthe$^{35}$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 $g_p\mathrm{/}{g}_a=6.7$ 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 $\mathrm{\ell }=2$ forbidden matrix elements.
