Abstract

The role of shell effects in reactions forming the heavy element ²⁶⁶Sg was investigated using the Mass Angle Distribution technique. For the ³⁴S + ²³²Th reaction the doubly magic shell closure at ²⁰⁸Pb was found to strongly influence asymmetric quasifission, the exit channel at sub barrier energies. The evolution of the dinuclear system is arrested as it passes through this mass region. Mass splits corresponding to A_L/A_H Π 58/208 are seen for a large range of angles indicating a long timescale for this process. The more mass asymmetric ²⁸Si + ²³⁸U reaction has a much smaller quasifission cross section. Therefore the shell effects around ²⁰⁸Pb are not dominant here.
