- The linear thermal expansion coefficient α of solid deuterium with paramodification content of 2.25% was determined in the temperature interval 1.5-5.6 K. The contributions of the translational vibrations of the lattice αlat and the rotational motion of the molecules αrot to α are separated. The temperature dependence of αlat was determined by the expression αlat =1.475 · 10 - 7 T3+(4.5-7) · 10 - 10 T5. The possibilities of a universal description of the thermal expansion of cryocrystals with a central interaction, including quantum crystals of hydrogen isotopes, are discussed. A theoretical description is proposed and the temperature dependence of αrot is analyzed.
