High resolution spectral measurements of light charged particles (LCP) emitted during thermal neutron-induced fission of ²⁵²Cf^* (E^* = 6.2 MeV) have been performed with the recoil mass-separator LOHENGRIN. LCP emission yields, their mean kinetic energies and widths have been obtained for nuclear charges Z ≥ 2. For this compound nuclear system isotopic data for LCPs with Z ≥ 3 are presented for the first time. Emission of LCPs with masses up to A = 36 has been observed, the heaviest ternary particle measured so far in low-energy fission.
