Since its discovery, now 40 years ago, light (charged) particle-accompanied fission (often called ternary fission) has been extensively studied for spontaneous as well as for induced fission reactions. The reason for this interest was twofold: (1) the ternary particles being emitted in space and time close to the scission point were expected to supply information on the scission-point configuration (e.g., nuclear shapes and initial fragment and particle energy at scission), and (2) the ternary fission process turned out to be an important source of helium, tritium, and hydrogen production in nuclear reactors, for which data were requested by the nuclear industry.
