摘要: Abstract Electromagnetic-induced fission of several neutron-deficient actinides and pre-actinides was studied at GSI Darmstadt by use relativistic secondary beams. The characteristics multi-modal nuclei around 226Th are systematically investigated interpreted as the superposition three channels. Properties these channels have been determined for 15 systems. A global view on properties including previous results is presented. positions asymmetric found to be constant in atomic number over whole range systems investigated.
