Description
The synthesis of superheavy nuclei (SHN) with heavy ion collisions is modelled as a three staged model: capture, formation and survival, where this presentation explores the first two stages. Starting from the model in [1], the memoryless Brownian random walk was replaced by a Markov chain approach yielding significantly faster calculations which was then used to determine the cross sections in the production of SHN with deformed nuclei as targets [2]. In the presentation I show the results of this work that is presently being extended to yield systematic cross section predictions for different combinations of targets and projectiles [3]. To be able to present preliminary cross section results, the KEWPIE2 code is used for computing the survival probability [4].
