THERMOSTATIC PROPERTIES OF SEMIINFINITE POLARIZED NUCLEAR-MATTER

The surface and curvature properties of semi-infinite polarized nuclea r matter (SPNM) are calculated using an expansion for the Fermi integr als up to T-2. A density matrix expansion is obtained for a modified f orm of the Seyler-Blanchard interaction. New parameters that character ize the surface and curvature properties of SPNM are introduced. The l evel density parameter is extracted from the low temperature expansion of the free energy and compared with previous calculations. A reasona ble agreement is obtained with the parameters calculated before.
