Origin of molecular and isomeric minima in the fragmentation potential of the 296Lv superheavy element

摘要

The fragmentation potentials for for the 296Lv superheavy element are determined within two formalisms for comparison purposes.One is computed within the Woods-Saxon two center shell model and another within the one center shell model.Within the two center shell model two isomeric minima and a molecular min- imum for alpha decay are obtained in the potential landscape.The second isomeric minimum located close to the Pb channel and the molecular minimum belonging to the alpha-decay are not evidenced by calculations made with the one center shell model.We conclude that the two center shell model is more appropriate for the treatment of very asymmetric disintegration processes and of the scission configurations than the one center shell model.
