Coupled-channels analysis of silicon-nickel fusion reactions

Coupled-channels calculations are carried out for the series of ${}_{}{}^{28}{}_{}{}^{}$30Si${+\mathit{}}^{58}$6264Ni fusion reactions. The low-lying excitations of the projectile and target nuclei are taken into account within the rotational and vibrational models, respectively. The effects of one- and two-nucleon transfer reactions are included in the calculations using approximate methods. A good overall agreement with the data is obtained. The fusion cross sections apparently reflect changes in the radii of the nickel isotopes suggested by Hartree-Fock calculations.
