Abstract

A systematic analysis of hot fusion reactions with a comparison to experimental cross sections related to the synthesis of superheavy elements is carried out using the HIVAP code. A single parameter set is found which when implemented in the HIVAP computer code, describes experimental production cross sections for reactions using a 48Ca beam on actinide targets reasonably well. A simple scaling based on the mass asymmetry of the projectile-target system is introduced for projectiles lighter than 48Ca. It is seen that only three parameters scaled by a constant factor are required to describe cross-section data obtained using lighter projectiles. The projectiledependence on the production cross section is also studied. From these investigations, new reactions with 48Ca incident on various actinide targets are proposed for the production of unknown heavier isotopes of Z = 116 and 118 and for the synthesis of new superheavy elements with Z = 119 and 120
