Experimental investigation of fusion of Li7+Si28 above the Coulomb barrier
Abstract
Excitation functions for the above-barrier fusion cross sections are measured for the first time for the Li7+Si28 system by two methods—the characteristic γ-ray method and the evaporation α measurement method—in the energy range Elab=11.5-26 MeV. Experimental results are consistent and agree with each other, and the one-dimensional Barrier Penetration Model (BPM) predictions describe the data well up to twice the Coulomb barrier, but they overestimate the data by about 15 20% at higher energies.
