Résumé
Les propriétés de la matière nucléaire ont étées étudiées dans le cadre de la théorie de Brueckner a température finie. L'énergie d'une particule a été calculée en manière autoconsistante utilisant une représentation séparable du potentiel de Paris. Les résultats à une température donnée sont comparées avec ceux obtenues à la même température en congélant la matrice G à T = 0. En reproduisant nos résultats par une interaction du type de Skyrme on a estimé les paramètres correspondantes à différentes températures.


Abstract
The properties of hot nuclear matter are investigated in the framework of the finite temperature Brueckner theory. The single-particle energy has been self-consistently evaluated using a separable representation of the Paris N-N potential. The results at a given temperature are compared with those obtained at the same temperature with the G-matrix frozen at T = 0. Fitting these results with a Skyrme-like interaction the corresponding parameters have been estimated at different temperatures.





What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
