[en] The classical dynamical calculations of the collisions of two heavy ions leading to their fusion are presented. An extra and extra-extra push energies for different combinations of the target and projectile ion are established. A scaling which goes with an arithmetic average of the fissility and the effective fissility parameters is proposed. (author)

[en] We present an atlas of 665 deformation-energy maps and 150 maps of other properties of interest, relevant for nuclear systems idealized as uniformly charged drops endowed with a surface tension. The nuclear shapes are parametrized in terms of two spheres modified by a smoothly fitted quadratic surface of revolution and are specified by three variables: asymmetry, sphere separation, and a neck variable (that goes over into a fragment-deformation variable after scission). The maps and related tables should be useful for the study of macroscopic aspects of nuclear fission and of collisions between any two nuclei in the periodic table

[en] This is theoretical study stimulated by recent experiments at the 88-Inch Cyclotron on the binary decay of the light composite systems ⁴⁶V, ⁴⁹Cr and ⁵²Fe produced in collisions of ⁶Li, ⁹Be, and ¹²C with ⁴⁰C. The dynamics of the collision is followed using the chaotic regime idealization (Liquid-Drop potential energy, wall-and-window dissipation and Werner-Wheeler inertia). Parametrization of the nuclear shapes and angular momentum are included. According to the model calculations, the decay of these systems is predicted to be the result of the fission of a rotating super-deformed configuration. The calculations suggest an angular momentum window for this type of reaction between about 30 Planck's Constant and 43 Planck's Constant. The relevant saddle-point configurations are close to scission and there is relatively little damping before fission

[en] The branching ratios of the lifetimes for the radioactive decay of nuclei by the emission of alpha particles and heavier nuclei like ¹⁴C are estimated. Calculations are based on the idea that these decay modes can be treated as extremely asymmetric fissions. The potential barriers are calculated as a Coulomb potential plus Yukawa plus exponential folded potential. The comparison with a recently observed branching ratios between alpha particle decay and ¹⁴C emission from ²²²Ra, ²²³Ra and ²²⁴Ra shows that the agreement is within one order of magnitude. 7 refs., 5 figs., 2 tabs.
