Transfer cross sections for58Ni+58Ni and58Ni+64Ni in the vicinity of the fusion barrier

Transfer cross sections have been measured for ${}_{}{}^{58}{}_{}{}^{}$Ni${+\mathrm{}}^{58}$,64Ni in the energy range $E_{\mathrm{c}.\mathrm{m}.\mathrm{}=100\mathrm{}–}$107 MeV with use of time of flight in a magnetic spectrograph. The direct reactions are dominated by one-neutron transfer, with other transfer cross sections being smaller by a factor of 3–4 or more. The average kinetic energy loss is ∼2 MeV. Over the measured energy range the total transfer cross section for ${}_{}{}^{58}{}_{}{}^{}$Ni${+\mathrm{}}^{58}$Ni is smaller than that observed for ${}_{}{}^{58}{}_{}{}^{}$Ni${+\mathrm{}}^{64}$Ni by a factor of 4.
