Abstract:	⁷³As(⁷³Ge) Mössbauer emission spectroscopy is used to ascertain that the transition of the (Pb_0.4Sn_0.6)_0.86In_0.14Te solid solution to a superconducting state is accompanied by a change in electronic density at the cation sites, and spatial inhomogeneities in the Bose condensate of Cooper pairs are revealed.
