Ternary particles of Z =1 to 4 emitted in spontaneous fission of 252Cf

This paper presents the results of ternary light charged particles from 252Cf spontenous fission source. The method DeltaE - E was applied to identify particle by a position sensitive telescope.The specific energy loss (DeltaE) measured using transmission type detector (thicknesses 150 μm ) ordered company Micron Semiconductors, while residual (E) Timepix with thicknesses 600 . It possible measure partial-energy spectra various types due Al foil (31 μm) and (150 placed before detector. spectrum protons qualitatively different other since Al(n,p) Si (n,p) reactions could contribute spectra.
