The structure factor is used to identify the possible phases of the system. At intermediate temperatures, evidence for the presence of an additional incommensurate phase with a varying wavevector between the disordered and antiphase states is given. © 1989 IOP Publishing Ltd.EnglishArticle10.1088/0305-4470/22/18/031
