The total deformation energy at the moment of the neck rupture for the heaviest nuclei for which SF has been detected (<sup>279–281</sup>Ds, <sup>281</sup>Rg and <sup>282–284</sup>Cn) is calculated using the Strutinsky’s prescription and nuclear shapes described in terms of Cassinian ovals (defined by an elongation parameter α=0.98) generalized by the inclusion of four additional shape parameters: α<sub>1</sub>, α<sub>3</sub>, α<sub>4</sub>, and α<sub>6</sub>. Supposing that the probability of each point in the deformation space is given by Boltzmann factor, the distribution of the fission-fragment masses is estimated. The octupole deformation α<sub>3</sub> at scission is found to play a decisive role in determining the main feature of the mass distribution: symmetric or asymmetric…< Réduire
