Properties of the superconducting state in compressed Sulphur
The thermodynamic properties of the superconducting state in Sulphur under
the pressure at 160 GPa were determined. It has been shown that: (i) the
critical value of the Coulomb pseudopotential is equal to 0.127; (ii) the
critical temperature (T_{C} =17 K) should be calculated by using the modified
Allen-Dynes formula; (iii) the effective electron-electron interaction is
attractive in the range of frequencies from zero to the frequency slightly
lesser than the maximum phonon frequency (~ 0.85\Omega_{max}); (iv) the
dimensionless ratios 2\Delta (0)/k_{B}T_{C}, $\Delta C(T_{C})/C^{N}(T_{C}) and
T_{C}C^{N}(T_{C})/H^{2}_{C}(0) are equal to 3.7, 1.65 and 0.16 respectively;
(v) the ratio of the effective to bare electron mass reaches maximum of 1.77
for T=T_{C}.Comment: 3 pages, 5 figure
