Abstract
Hard-photon (Eγ> 30 MeV) emission from second-chance nucleon–nucleon bremsstrahlung collisions in intermediate energy heavy-ion reactions is studied employing a realistic thermal model. Photon spectra and yields measured in several nucleus–nucleus reactions are consistent with an emission from hot nuclear systems with temperatures T≈4–7 MeV. The corresponding caloric curve in the region of excitation energies ϵ★≈3A–8A MeV shows lower values of T than those expected for a Fermi fluid.
