- Abstract
In Coulex experiments at intermediate beam energies besides electromagnetic forces the nuclear interaction may occur. These two excitation mechanisms result in emission of γ-rays with a characteristic angular distribution W(θ). Measurement of W(θ) 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.
