It is shoxvua in tlae 3-rd virial approxirnatioua tlaat tlae smectic A-crystalliuae phasetransition occurs in perfectly aligxaed idematical rigid cylinders (or discs) witla diameterD auad length L, by using tlae naetltod of s3'xnmetry breaking potential. TIICI suaaectic Aphase and a laexagonal crystalliuae pltase are s]?ow'n to co-exist for 0,39<j<0.53,where t7 denotes the packiuag fraction. Nut tlue co-existence region, tlae crystallixte latticeconstants *:1.35D in tlae lvexagonal plauae and c', I.26L alc>ng the 1101-11181 to theplane and the smectic lad'er spaciuag /:,1.35L are obtained. The hexagonal columnarphase is SIIOWII to be more stable tltan tlae smectic A plaase at higlter deuasity tlaan'ZSmA-Cal""' but always less stable tlaaua the crystalline phase. 'Tlaese results are in de-pendent of tlte ratio DSL due to t1?e asst.?mption of perfectly parallel aliguanaent ofnaolecules.
