The paper discusses the feasibility of experimental determination of the Weinberg angle through the determination of the P-odd anisotropy ..cap alpha../sub e/, induced by the weak neutral muon-nucleus interaction, in the angular distribution w(theta) = 1+..cap alpha../sub e/ cos theta of the electrons emitted in the conversion of the 2s..-->..1s muon transition in the electron shell of the ..mu../sup -/ muonic atom. Realistic calculations of the probabilities for conversion in Ns electron orbits (N = 1, 2, 3, and 4) and the electronic enhancement factors Phi for the P-odd effect are carried out for a number of electronic configurations of muonic atoms in the region 2< or =Z< or =21 (where Z is the nuclear charge) within the framework of the relativistic variant of the Hartree-Fock-Slater method (with Latter's correction). The factors Phi are found to depend weakly on the electronic configuration of the muonic atom and the quantum number N, and this significantly simplifies the problem of theoretical interpretation of the observed value of ..cap alpha../sub e/.
