ResumenThe symmetry energy and its temperature dependence for isotopic chains of even-even Ni, Sn, and Pb nuclei is studied in the framework of the local density approximation (LDA). The Skyrme energy density functional with two Skyrme-type effective interactions, SkM* and SLy4, is used in the calculations. The temperature-dependent local proton and neutron densities, as well as the kinetic energy densities, are calculated through the HFBTHO code that solves the nuclear Skyrme-Hartree-Fock-Bogoliubov problem by using the cylindrical transformed deformed harmonic-oscillator basis. In addition, two other density distributions of 208Pb, namely the Fermi-type density determined within the extended Thomas-Fermi (TF) method and symmetrized-Fermi local density obtained within the rigorous density functional approach, are used. Alternative ways to calculate the symmetry energy coefficient within the LDA are proposed. The results for the thermal evolution of the symmetry energy coefficient in the interval T = 0–4 MeV show that its values decrease with temperature. The temperature dependence of the neutron and proton root-mean-square radii and corresponding neutron skin thickness is also investigated. The results show that the larger temperatures lead to a substantial increase of the neutron radii and skins.
