Spontaneous and induced fission of very heavy and super-heavy nuclei

In the 2nd semester of 2018 the superheavy element factory [1] at JINR (Dubna) will deliver its 1st intense beam of 48Ca and experiments using a new gas filled separator and new detection modules will be carried out. The purpose is to study in details the nuclear, atomic and chemical properties of very heavy and superheavy elements with considerably improved statistics. Among the decay properties of these nuclei, particular attention will be given to nuclear fission. In the same period the SPES facility, under development at the Laboratori Nazionali di Legnaro, is expected to enter the production stage of neutron-rich radioactive beams. With these beams the study of fission in unexplored regions of the nuclear chart will be possible, in particular in the region of very heavy neutron rich nuclei. During the Workshop the existing theoretical and experimental results concerning fission and quasifission (such as fission barriers, half-lives, branching ratios, hindrance factors, mass and TKE distributions) will be reviewed, and emphasis will be given to the study of fission and quasifission in unexplored regions of the chart of nuclei, like the terra incognita or the new island of stability, which are of profound interest for the stellar nucleogenesis and for the understanding of the survival of the shell effects.
