Features of low-temperature plasticity of solid hydrogen

A substantial dependence of the rate of the steady-state creep of H2 at helium temperatures on the ortho-para composition of the samples has been observed. When the concentration of the ortho modification is decreased to 0.2%, the rate of deformation of the hydrogen increases by more than 50 times.
