Experimental Observation of Second Phase Transition in Solid CH
Krupskii I. N., Prokhvatilov A. I., Gasan V. M.
Precision x-ray investigations of the temperature dependence of the lattice parameter of methane were performed in the interval 6 lU°K. A volume jump of approximately 0.15? was observed at Τ = 9.9 ± 0.2°K.
