Abstract

Predictions based on the "Fusion by Diffusion" model in a version adapted for calculating xn channels, with the ground-state masses, shell effects and barrier heights as given by Muntian, Patyk and Sobiczewski are presented. Sensitivity of the model to uncertainties in determination of the theoretical fission barriers is discussed. Predictions concerning formation of the element Z = 120 include comparison of fusion of the most asymmetric systems, ⁵⁰Ti + ²⁴⁹Cf and ⁵⁴Cr + ²⁴⁸Cm, with less asymmetric combinations ⁵⁸Fe + ²⁴⁴Pu and ⁶⁴Ni + ²³⁸U.
