Abstract
In Coulex experiments at intermediate beam energies be sides electromagnetic forces the nuclear interaction may occur. These two excitation mechanisms result in emission of gamma-rays with a characteristic angular distribution W(theta). Measurement of W(theta) was performed at the RISING fast beam set-up to probe the electromagnetic-nuclear interface. Unexpectedly large hadronic-like contribution was observed when high Z projectiles were used.Pubblicazioni consigliate
