Calibration of the Ruby-Pressure-Scale at Low Temperatures
R. A. Noack,W. B. Holzapfel +1 more
TL;DR: In this article, the same physical reasons which are responsible for the temperature dependence of the R lines at normal pressure could also lead to a Variation in the pressure dependence of these lines with temperature.

Compression of solidified gases to 20,000 kg/cm2 at low temperature
TL;DR: The relative volume decrease as a function of pressure has been measured for solid He, H2, D2, and Ne at 4°K, for N2 and A at 65°K and for A at 77°K by the direct piston displacement method of B ridgman as mentioned in this paper.
