Abstract
Heavy-ion fusion barrier distributions are now routinely obtained directly from experimental data. By measuring the total gamma-ray multiplicity for the Ni-58 + Ni-60 system, which has a striking yet well understood barrier distribution, we show that some evidence of the barrier structures is present in the derived spin populations. In particular, very high spins can be populated at energies rather close to (and even below) the 'nominal' Coulomb barrier. (File in questo prodotto:
