Examining empirical evidence of the effect of superfluidity on the fusion barrier

NUCLEAR REACTIONS ^90,96Zr(⁴⁰Ca, X), E=87-105 MeV; ¹²⁴Sn(⁴⁰Ca, X), E=107.5-125.5 MeV; ¹⁶⁸Er(³⁴S, X), E=110-135 MeV; ²⁰⁸Pb(¹⁶O, X), E=70-82.5 MeV; ⁷⁴Ge(¹⁸O, X), E=30-47.5 MeV; calculated σ(E), fusion barrier distribution using CCFULL code with local regression, and integral methods; deduced enhancement of the fluctuations of the fusion barrier between superfluid nuclei. Systematically evaluated 115 fusion reactions. Comparison with experimental values, and with time-dependent Hartree-Fock-Bogoliubov (TDHFB) predictions.
