    "abstract": "It has been proposed that the discrepancy between the partially-conserved\naxial-current prediction and the nuclear shell-model calculations of the ratio\n$C_P/C_A$ in the muon-capture reactions can be solved in the case of ^{28}Si by\nintroducing effective transition operators. Recently there has been\nexperimental interest in measuring the needed angular correlations also in\n^{20}Ne. Inspired by this, we have performed a shell-model analysis employing\neffective transition operators in the shell-model formalism for the transition\n$^{20}Ne(0^+_{g.s.})+\\mu^- \\to ^{20}F(1^+; 1.057 MeV) + \\nu_\\mu$. Comparison of\nthe calculated capture rates with existing data supports the use of effective\ntransition operators. Based on our calculations, as soon as the experimental\nanisotropy data becomes available, the limits for the ratio $C_P/ C_A$ can be\nextracted.",
