| Abstract: | Expressions for the isothermal bulk and shear modulus and also their first and second order pressure derivatives for rare gas solids are derived by a simple method considering the different interactions i.e. modified variable induce dipoles, short range overlap repulsion and the vibrational contribution. The derived relations for dKT/dP, dCS/dP, dC′44/dP, d2KT/dP2, d2CS/dP2 and d2C′44/dP2 are used to compute the numerical values of these constants at P=0 for Ne, Ar, Kr and Xe. |
