Thermal properties of asymmetric semi-infinite nuclear matter in the extended Thomas Fermi model

Abstract EN

This investigation starts from the free energy of Skyrme interaction and perform a leptodermous expansion for asymmetric semi-infinite nuclear matter system expanded in temperature up to T 4.

We got analytical formulae for the volume, surface and curvature free energies.

This liquid drop model formula i s us e d to study the thermal properties of asymmetric semi-infinite nuclear matter s ys tems .

The pressure isotherms of this system showed a liquid-gas phase transition.

We discussed the effect of volume, surface and curvature properties on the liquid-gas phase transition.

The effects of temperature on the volume, surface and curvature incompressibility are discussed.

In addition, the effects of the finite number of nucleons on the free energy, pressure and compressibility of the system are studied.
