The mixed spin-1/2 and spin-3/2 Ising model on the extended Kagome lattice is solved by establishing a mapping correspondence with the eight-vertex model. When the parameter of uniaxial single-ion anisotropy tends to infinity, the model system becomes exactly solvable as the staggered eight-vertex...
