First Results on Observation of New Shape Isomers

In our previous publications devoted to the collinear cluster tri-partition (CCT) of the low excited nuclei [1,2] we have discussed the role of scattering medium in the registration of the CCT products. This decay mode has been called by us “collinear cluster tri-partition” (CCT) in view of the observed features of the effect, that the decay partners fly apart almost collinearly and at least one of them has magic nucleon composition. Briefly, even if initially two CCT partners fly in the same direction perfectly collinearly they get some angular divergence after passing the scattering medium on the flight pass due to the multiple scattering. Thanks to such effect they can be registered independently in the “stop” mosaic detector. Actually even thin backing of the radioactive source provides the observable effect.
