Formation mechanism of decay fragments in spontaneous ternary fission of heavy nuclei

RADIOACTIVITY ²⁵²Cf(SF); analyzed available data; deduced a model for describing spontaneous ternary fission of heavy nuclei, dominance of the collinear cluster tripartition process observed in FOBOS experiments, competition between binary fission and the formation of a trinuclear system.

Analysis of the fusion mechanism in the synthesis of superheavy element 119 via the ⁵⁴Cr + ²⁴³Am reaction

NUCLEAR REACTIONS ²⁴³Am(⁵⁴Cr, 2n), (⁵⁴Cr, 3n), (⁵⁴Cr, 4n), E(cm)=261 MeV; calculated driving potential for the DNS, dependence of the quasifission barrier on the charge asymmetry of the DNS, charge distribution of the DNS fragments, partial and total σ for complete fusion, quasifission, fast fission, and evaporation residues formation for Z=119 super-heavy nuclei (SHN). ²⁴³Am(⁴⁸Ca, xn), E(cm)=190-225 MeV; calculations for ²⁴³Am+⁵⁴Cr reaction verified by comparison of theoretical and experimental σ(E). Combined dinuclear system (DNS) model and statistical model incorporated in KEWPIE2 code for SHEs.
