RESUMO

The technique of molecular dynamics together with lattice dynamics was used to estimate the effects of the anharmonicity of the ion-ion pair potential to hermodynamics functions in RbK alloys. The same technique was used to calculated the total static structure factor in NaCs alloys. The effective ion-ion pair potentials in these alloys was calculated by an extension of the pseudo-potential formalism applied to the alkali metals, with appropriated odifications to the alloys. These potentials,associated to the molecular dynamics, reproduced, to the RbK alloy, the experimental data of the normal and local modes frequency and the experimental total static structure factor in NaCs alloys
