A study of the dependence of the giant dipole resonance {gamma}-ray yield from different functional forms of the symmetry term for the nucleon-nucleon interaction potential has been performed through the semiclassical molecular dynamics approach CoMD-II. We studied central and midperipheral reactions in the charge/mass asymmetric system {sup 40}Ca+{sup 48}Ca at 45 MeV/nucleon. The calculations show that the balance between the dynamical and the statistical emission is very sensitive to the 'stiffness' of the symmetry term. This sensitivity could be highlighted by measuring the degree of coherence and the anisotropy ratio related to the dynamically emitted radiation.
