Summary

The potential energy for a crystal of orthorhombic sulphur has been calculated as a function of the unit-cell parameters, by using potential functions which take into account S-S interactions between nonbonded atoms. The results show that the unit-cell parameters may be predicted successfully when an Ar-Ar potential function, proposed by Mason and Kreevoy, is used.

Riassunto

Si calcola l’energia potenziale in un cristallo di zolfo ortorombico in funzione dei parametri della cella elementare, usando funzioni di potenziale per descrivere interazioni tra atomi di zolfo non direttamente legati. I risultati mostrano che i parametri della cella elementare possono essere predetti con ottima approssimazione quando si usa una funzione di potenziale proposta da Mason e Kreevoy per gli atomi di argon.
