Abstract

Three fimdamental types (named A-, B- and O-type) in the fragment mass-yield distribution and three independent types of the scission deformation (β∼1.65, 1.53 and 1.33) for actinide nuclei in fission process are experimentally observed. The correlations between the final shapes of fissioning nuclei and the shapes of the fragment mass-yield distributions are hence revealed and presented. A>-type: deformation path with β∼1.65 resulting in a typical FWHM of >20 u; B-type: deformation path with β∼1.53 leading to a typical FWHM of ∼15 u; O-type: deformation path with β∼1.33 producing a FWHM of ∼9 u.
