Sažetak
The fusion excitation function of 58Ni + 54Fe has been measured in a cross sections range from ~1 microbarn up to around 450 milibarn. Coupled-channels calculations, using a standard Woods-Saxon ionion potential, reproduce the excitation function down to about 180 microbarn. At lower energies, fusion cross sections drop faster than calculations, with a steep slope. The astrophysical S factor shows a maximum at the lowest energies. These results are compared with various evidences coming from recent experiments on other systems with projectile and target in the mass range A~30-60.
