An estimate is given of the intensity of the satellite lines of the 2s/sup 1/2/..-->..1s/sup 1/2/ radiative transition in a mesic atom due to configurational interaction between the meson and the shell electrons of the mesic atom. It is shown that the intensity of these satellite lines is by approximately six orders of magnitude greater than the intensity of the radiation in a 2s/sup 1/2/..-->..1s/sup 1/2/ meson transition. The necessity to exclude the satellite lines in an experiment aiming to observe nonconservation of parity requires an energy resolution for the quantum detector of ..delta..h..omega../h..omega..< or =10/sup -4/. The effect of the configuration interaction between a meson and the electrons of the conduction band in metals does not allow us to utilize metal targets for stopping the mesons in such an experiment. In the case of formation of a mesic atom in a gaseous medium the Stark effect of the electric field of the dipole induced in the collision of an atom of the medium with the mesic atom (Z> or =2) stripped of electrons, and the Stark effect of the intra-atomic field in the case of a collision of a ..mu..H atom with an atom of the medium, as shown by the estimates that have been made, give essential upper limits on the density of the medium respectively of the order of < or =10/sup 14/ at/cm/sup 3/ and < or =10/sup 11/ at/cm/sup 3/.
