Abstract
Four isotopes of rutherfordium, , were produced by the and reactions () at the Lawrence Berkeley National Laboratory 88-Inch Cyclotron. Excitation functions were measured for the and exit channels. A maximum likelihood technique, which correctly accounts for the changing cross section at all energies subtended by the targets, was used to fit the data to allow a more direct comparison between excitation functions obtained under different experimental conditions. The maximum cross sections of the and reactions obtained from fits to the experimental data are nb and nb, respectively. Excitation functions for the 2 exit channel were also measured, with maximum cross sections of nb for the induced reaction, and nb for the induced reaction. The impact of the two neutron difference in the projectile on the cross section is discussed. The results are compared to the Fusion by Diffusion model developed by Świa˛tecki, Wilczyńska, and Wilczyński.
