Energy spectra and yields were measured for /sup 3/H, /sup 4/He, /sup 6/He nuclei and Li and Be isotopes, released during spontaneous fission of /sup 252/Cf. Energy and angular distributions were determined for /sup 3/H, /sup 4/He, and /sup 6/He in coincidence with heavy fission fragments, in the range 60--120/sup 0/ of particle emission angles relative to the light fragment direction of motion. Mass distributions were obtained for heavy fragments in ternary fission, and energy and angular correlations were determined for charged particles and fission fragments in the range 1.0--2.0 of mass ratios. The experimental data are compared with analogous results obtained from detailed investigation of thermal-neutron-induced fission of /sup 235/U with emission of ..cap alpha..-particles, and with existing trajectory calculations for ternary fission of nuclei.
