Özet

The recently obtained analytical result [1] for renormalization of the jump of the heat capacity (C-S - C-N)/C-N by anisotropy of the order parameter is applied to the layered superconductors. The graph of (C-S - C-N)/C-N vs. the anisotropy of the order parameter allows a direct determination of the gap anisotropy in MgB2 using available experimental data.
