Isothermal bulk modulus of solid xenon for zero pressure at 4.2 K, 65 K and 77 K

An interferometric method has been used to measure the isothermal bulk modulus (the reciprocal of the compressibility) of solid xenon at zero pressure for several temperatures. It is the first time that an elastic constant of this substance has been measured at a temperature below 10 K. The smoothed results are (37.9 ± 0.5) kbars at 4.2 K, (29.6 ± 0.5) kbars at 65.6 K, and (28.2 ± 0.5) kbars at 77 K.
