- and others
Cross sections for evaporation residue production have been measured for the systems {sup 58,64}Ni + {sup 78,86}Kr and {sup 58,64}Ni + {sup 92,100}Mo at energies below and above the Coulomb barrier. Coupled-channels calculations including one-and two-phonon excitations of low-lying collective states in the projectile and target give excellent agreement for systems involving the closed shell nuclei {sup 86}Kr and {sup 92}Mo. Fusion cross sections for systems involving the transitional nuclei {sup 86}Kr and {sup 92}Mo, however, show an additional fusion enhancement indicating the need for the inclusion of higher order processes in the calculations.
