  • We measured natural ortho-para conversion rates within a wide region of hydrogen fluid states: at temperatures 17–32 K in the liquid and at temperatures 40–120 K in the gas for densities up to 0.09 g/cm3. The experimental data for the gas phase are interpreted within the framework of a theory, the basic distinction of which from Wigner’s approach is that we take into account the dependence of the closest distance in a collision of two orthomolecules on their velocity (i.e., temperature). Our… CONTINUE READING
