Simmons, R.O. Schwalbe, Larry Allen 2012-04-19T18:48:59Z 2012-04-19T18:48:59Z 10000-01-01 1973 The direct technique of simultaneously measuring bulk and lattice expansion to determine equilibrium vacancy concentrations, has been applied to solid argon. The results indicate that vacancy concentrations do not exceed 0.02% even at the highest temperatures. Although the data obtained were not sufficiently precise to allow unique values to be determined for the formation parameters, it would appear from semiempirica1 considerations that both these results and previous ones, from the similar investigation of solid krypton, cannot be explained consistently within the context of presently existing theory.
