| Abstract: | A approximate method combined the mean - field renormalization group theory (MFRG) and the discrerised path - integral representation (DPIR) is employed in the study of the spin - 3/2 transverse Ising model in a trimodal random field (RFTIM). The phase diagram and some critcial properties are obtained and discussed. |
