The exact solutions of the spin-spin correlation functions, the internal energy and the specific heat in a mixed spin Ising chain made up of two kinds of alternating magnetic atoms, namely spin-1/2 atoms and spin-S (S>1/2) atoms with a crystal-field interaction constant D, are derived by the use of Ising spin identities and a differential operator technique. These solutions are valid for arbitrary values of S and D. some numerical results are given for the specific heat. We find that the results exhibit characteristic behavior which does not follow the Schottky-type when the value of D becomes smaller than a (negative) critical value.
