In this study, the energy spectra and yields of various ternary and quaternary particles produced during the spontaneous fission of &sup(252)Cf were measured and analyzed. Particles with atomic numbers Z = 1 to 6 were clearly identified, including hydrogen and helium isotopes such as *1H, *2H, *3H, *4He, *6He, and *8He. Distinct energy distributions were observed for each particle type, and Gaussian fitting was applied to estimate their yields and energies. The analysis successfully quantified the yields of ternary particles, including *1H, *2H, *3H, *4He, *6He, *8He, as well as heavier fragments like lithium (Li), beryllium (Be), boron (B), and carbon (C). In addition to ternary particle emissions, this study investigated quaternary fission (QF) processes in &sup(252)Cf. Two main pathways were identified: pseudo-quaternary fission, resulting from the decay of unstable light charged particles (LCPs) such as *7Li, *8Be, and *9Be*, and true quaternary fission, characterized by the independent emission of two LCPs. Angular distributions of *a-particle coincidences from *8Be decays were analyzed, and the results aligned with the predicted decay kinematics of *8Be from both its ground and first excited states. Although the statistics were limited, the energy spectrum of (*a, t) pairs from the second excited state of *7Li was successfully analyzed and compared to the ternary Li particle data. The study reported yields and energy spectra of particles from these processes
