Résumé
Nous avons obtenus des solutions Jastrow-HNC optimales sans paramètres pour l'hydrogène atomique 1 spin polarisé. Nous avons calculé l'énergie fondamentale, la fonction de diffusion inélastique, la fonction de structure ainsi que la fraction condensée de Bose Einstein. Les excitations élémentaires et la stabilité du système ont été étudiées par des méthodes empruntées à la théorie de l'4He liquide.
Abstract
Non parametrized, optimal Jastrow-HNC solutions have been obtained for condensed spinaligned atomic hydrogen. Accurate values have been calculated for the energy, the pair correlation and the structure function as well as for the Bose condensate fraction. The elementary excitations and the stability of the system have been studied using methods adapted from the theory of liquid 4He.
