For both compounds, the obtained temperature-behavior of the specific heat well describes the experimental data. We compare our findings with the \"two-band - model\" that is frequently used to calculate the electronic specific heat, and that is applicable only for superconductors with strong interband scattering (\"dirty\" enough superconducto","authors_text":"A.E.Karakozov, B.P.Gorshunov, E.G.Maksimov, E.S.Zhukova, M.Dressel, Ya.
