Statistical emission of high-energy photons in heavy-ion reactions 20Ne+12C \to 32S at 5.2 MeV/u and 19F+12C \to 31P at 4.4 MeV/u has been studied and the Giant Dipole Resonance strength functions in 32S and 31P at excitation energy of 58 and 55 MeV have been extracted. Possible isospin and deformation splitting of the GDR are discussed. The derived isospin mixing coefficient for 32S states at 58 MeV excitation is presented.
