摘要

Fusion, fission and cluster radioactivity are predicted as cold nuclear phenomena, prior to experiments, on the basis of the quantum mechanical fragmentation theory. The fundamental result of the theory is the role of (spherical) closed shell effects of one or both the reaction partners for fusion, or decay products for fission and cluster radioactivity. Also, not only that deformed nuclei are used in fusion experiments, not precluded by the theory, and high neutron multiplicity fission data is observed to be associated with hyper-deformation of the fission fragments, more recently, it is shown that static deformations of nuclei also play an important role in the interpretation of available cluster radioactivity data on the basis of the dynamical preformed cluster model. In view of such results, the role of deformation and orientation effects of the two colliding nuclei is studied here for the colliding nuclei to be in the same plane (co- planar) or different planes (non-coplanar). The aim is to look for the best cold reaction valleys for the synthesis of new and superheavy elements, using non-coplanar collisions, in future experiments. The illustrative examples are the excited compound nuclei 286 112 * and 292 114 * .
