The Lattice Constants of the Inert Elements

A B L E interest attaches to measurements of the lattice constants of solidified inert gases a t low temperatures because of the opportunity in C this relatively simple case of deducing information on the form of the lau of force between molecules.Nevertheless, techniques for the measurements are not easy and the published observations, mostly at isolated temperatures, shon inconsistencies among themselves.In table 1 are collected together the results giyen by Simon and Ruhemann (1932) (SR), and by Natta and Nasini (1930) ( N x ) for xenon and krypton, and by Keesoni and Raooy (1930) (KRI) for krypton,
