Bimodality and charge (mass) splitting in fission of actinides — •A.V. Andreev^1,2, G.G. Adamian^2,3, N.V. Antonenko^1,2, S.P. Ivanova², and W.

Fission of actinides is described within the scission-point model. Scission configurations are interpreted as dinuclear systems (DNS). The potential energy surfaces of scission configurations are analyzed as functions of deformations of the DNS fragments by considering mass and charge asymmetries as independent variables. It is demonstrated that bimodality in fission of actinides at fixed mass splitting is related to different charge splittings. Experiments are suggested to prove this interpretation of bimodality.
