    California at San Diego, La Jolla, California 92093 (Received 29 September 1989) The free energy of the classical ,,;,= 178--180. This paper presents an analytic calculation of the free energy of the solid phase for both bcc and face-centered-cubic (fcc) lattices. The 0( T ) term in the free energy gives the lowest
