Abstract
We have measured the melting curve of neon to 54.5 kbar and 328 K using a diamond‐anvil cell. The measured points together with earlier low‐pressure data are fitted accurately with a Simon‐Glatzel function. Theoretical calculations of the melting curve using lattice dynamics and variational fluid theory with exponential‐six potentials fitted to solid isotherm data are in good agreement with the experimental data. The law of corresponding states is tested for the melting curves of He, Ne, and Ar, and is found to be obeyed.
