Description
The mass distributions of 252Cf(sf) ternary fission fragments with the emission of a light charged particle are measured. The experiment was carried out on a modernized COMETA time-of-flight spectrometer consisting of 28 silicon pin diodes with a thin input window and a starting detector based on microchannel plates. The threshold for the measured particle energy was ~1 MeV. The mass resolution for alpha particles was ~0.34 amu. It was found for the first time that in fission events with alpha particles emitted at an angle close to 90° to the fission axis, a fragment passing through the emitting foil of the starting detector loses mass up to 16 amu. decay [1-4].
