Sažetak
In recent years, a puzzling pattern has been observed in fusion cross sections well below the Coulomb barrier, characterized as a departure from the exponential-like behavior predicted by standard coupled-channels models, known as fusion hindrance. We report on recent fusion measurements performed at the Laboratori Nazionali di Legnaro, in particular the 48Ca+48Ca reaction down to the level of 0.6 µb. Unlike most recent results in this field, we do not observe the typical divergent behavior of the logarithmic derivative ; but rather a sort of saturation, albeit at a larger value than predicted with a standard nucleus-nucleus potentia
