Comparative analyses between p-H2 and o-D2 submonolayer films adsorbed on graphite foam: heat capacity measurements

We analysed the results obtained from our heat capacity measurements, for critical exponent, critical temperatures and densities, vibrational temperatures, entropies and phase transitions of orto-deuterium and para-hydrogen adsorbed on graphite foam in the temperature interval of 5-25 K up to 0.0767A-2, comparing these properties of the two isotopes with the results found experimentally by other authors. Whenever possible we refer to theoretical works related to the results. (orig.)
