Abstract
The thermodynamic properties of the superconducting state induced in metallic molecular hydrogen under the influence of pressure 347 GPa were determined. In particular, it has been shown that the critical temperature (TC) changes in the range from 120 to 90 K for μââã0.08,0.15ã, where μâ is the value of the Coulomb pseudopotential. Next, the energy gap near the temperature of zero Kelvin (2Î(0)) was calculated. It has been stated, that the dimensionless ratio 2Î(0)/kBTC slightly decreases with the increase of μâ from 3.98 to 3.84. In the last step, the ratio of effective electron mass (mâe) to the bare electron mass (me)) was determined. It has been proved that mâe/me takes its highest value equal to 1.96 for T=TC.
