Thermal damping width of the giant dipole resonance in hot nuclei
Physical Review C
An approach describing the thermal damping width of the giant dipole resonance ͑GDR͒ in hot nuclei is presented. The GDR is generated by the ph excitations within the finite-temperature random-phase approximation ͑FTRPA͒, while its damping at finite temperature arises from irreversible coupling of ph configurations to the thermal pp and hh ones beyond the FTRPA. A semimicroscopic unification of the quantal spreading and thermal damping widths is undertaken within the framework of motionaldoi:10.1103/physrevc.55.2872 fatcat:hzq4qk7karbs5nwowql7g6mkzq
