[en] Gamma-ray transition-energy spectra up to E/sub γ/approx. =33 MeV have been measured for the decay of the compound nucleus ¹¹¹Sn( populated at excitation energies up to E(approx. =100 MeV. Above E/sub γ/approx. =20 MeV an excess of gamma rays over the contribution from the isovector giant dipole resonance is observed in the energy range where the isovector giant quadrupole resonance built on excited states is expected. The width of the giant dipole resonance in /sup 108,111/Sn( shows a large increase with increasing nuclear temperature and angular momentum
