“…True ternary fission of heavy nuclei, which has been discovered in the experiments recently, occurs with much smaller probability (∼ 10 −3 ) compared to the binary fission [1][2][3][4]. These experimental studies of the decays in 252 Cf(sf,fff) [1] and 235 U(n th ,fff) [4] reactions with two fission fragment coincidences with two FOBOS-detectors [1] placed at 180…”
