Temperature dependence of symmetry energy of finite nuclei    [PDF]

J. N. De, S. K. Samaddar

The temperature dependence of the symmetry energy and the symmetry free
energy coefficients of atomic nuclei is investigated in a finite temperature
Thomas-Fermi framework employing the subtraction procedure. A substantial
decrement in the symmetry energy coefficient is obtained for finite
systems,contrary to those seen for infinite nuclear matter at normal and
somewhat subnormal densities. The effect of the coupling of the surface phonons
to the nucleonic motion is also considered; this is found to decrease the
symmetry energies somewhat at low temperatures.
