We investigate pygmy and giant dipole resonance (PDR-GDR) for the case of neutron rich soft nuclei {sup 68}Ni and heavy nuclei {sup 208}Pb using effective nucleon-nucleon Skyrme interactions SLy7 and KDEO at finite temperature. We use the mean-field theory (HF) and employ the random phase approximation (RPA) in a coordinate space. We then compare the PDR calculations for the different Skyrme interactions with their experimental results. We find that the PDR and GDR strength distribution depends sensitively on temperature, and especially for {sup 68}Ni the collective effects almost disappear at T = 4 MeV.
