Experimental thermal expansions for solid neon, 2?14 K

Abstract

Linear thermal expansion measurements are reported for free-standing samples of solid neon at temperatures from 2 to 14 K. After normalization, the results agree well with x-ray data in an overlap region between 8 and 14 K. The T = 0 Griineisen parameter 7'o = 2.58 (+_0.05) is in excellent agreement with the results obtained from high-pressure equation of state data. Smoothed thermodynamic functions for solid neon at saturated vapor pressure are tabulated, and inconsistencies in published high-temperature bulk modulus results are discussed,
