In this comprehensive study, the 4He, 10Be, 14C, 14N, and 16O, LCP-accompanied ternary fission of the 248Cf isotope has been investigated based on equatorial geometry fragmentation. Utilizing the Three-Cluster Model (TCM) and using the WKB approximation, the Q-values, the driving potentials (V-Q), the probability of tunneling through barrier, the yields and the decay constant λ for an extensive array of various fragments combinations with positive Q-values are calculated. After testing for all possible combinations, in order for refinement of our findings, combinations with the higher Q-values and considerable yields are selected for further analysis. Calculated results for each LCP were tabulated and also yields versus mass number of one fragment A1 are plotted for a detailed analysis. Our study not only contributes significantly to the understanding of ternary fission of 248Cf nucleus but also highlights the role played by the interaction potential for different LCPs and clear the importance of shell effects in the ternary fission process. The calculated results pave the way for future studies in nuclear physics, particularly in understanding of the complex dynamics of the nuclear ternary fission involving fixed LCP.
