ResumoThe experimental representation of the fusion barrier distribution from the second derivative, d2(Eσfus)dE2, was the basis for a series of precise measurements of the fusion excitation function. As an alternative approach, it has been proposed recently that the first derivative of the compound nucleus (CN) spin distribution is equivalent to d2(Eσfus)dE2. Multiplicity distributions for the reactions 64Ni+100Mo and 32S+110Pd have been measured making use of the Argonne/Notre Dame-BGO-array and GASP, respectively. In particular, the influence of fission on the high spin tail of the spin distribution and the consequences for the experimental representation of the distribution of barriers is discussed for 64Ni+100Mo.
