摘要
The ground state of the Face-Centered Rectangular (FCR) lattice gas model which may correspond to the adsorbate system on the BCC(110) plane is investigated by the use of the method of geometrical inequalities. The structure of the ground state at an arbitrary value of the particle density is determined in the case of the repulsive 1st neighbor interaction. Various ordered structures are obtained as the ground states of the model. On the basis of the present results, several examples of the adsorbate system on the BCC(110) plane are discussed in connection with the interactions between the adsorbates. © 1978, THE PHYSICAL SOCIETY OF JAPAN.
