Experimental investigation of the gamma-ray quasi-continuum emitted after alpha induced fusion reactions.

Various experimental investigations on the γ-ray cascades of the deexcitation after the 160Gd(α,xn)^(164-x)Dy reactions at bombarding energies of Eα=40-110 MeV are presented. Of special interest are the so-called quasi-continuum γ-rays, the first γ-rays emitted before the lower-lying states of the ground state bands are reached. Experimental knowledge on these quasi-continuum γ-rays supplies information on the structure of states at high excitation energy and large angular momentum. Especially the competition between microscopic excitation and collective excitation is of interest. ... Zie: Summary
