✦ Synopsis

A temperature dependence of the spreading width of a giant dipole resonance is studied in the framework of the Quasiparticle-Phonon Model extended to finite temperature using a formalism of the Therm0 Field Dynamics. Numerical calculations are performed for "'Sn and the neutron-rich double-magic isotope 13'Sn It is found that the dispersion of the El strength function 0 increases with temperature.
