The neutron thermal pairing gap determined from the modified BCS theory is included in the calculation of the width of the giant dipole resonance (GDR) at finite temperature T in 120Sn within the Phonon Damping Model. The results obtained show that thermal pairing causes a smaller GDR width at T ≤ 2 MeV as compared to the one obtained neglecting pairing. This effect improves significantly the agreement between theory and experiment including the most recent data point at T = 1 MeV.
