    "abstract": "The hyperfine effect in muon capture rate is analyzed with taking into\naccount of the second-order terms in 1/M in the non-relativistic Hamiltonian.\nIt is shown that in the situation of the dominance of the squared first-order\nterms the interference of zero-order and second-order terms has no significant\ninfluence. General expression for neutrino (recoil nucleus) angular\ndistribution in muon capture by nucleus with non-zero spin is proposed. High\nsensitivity to $g_P$ of the term related with alignment of the initial mesic\natom is discussed in the approximation of dominating Gamow--Teller matrix\nelement.",
