Note (General): Dust particles in plasma are self-organized due to strong Coulomb coupling. In order to explain the self-organization mechanism of dust particles in plasma, one-dimensional theoretical model is introduced. This model predicts variation of the Gibbs free energy against the distance between the dust particles. From the calculation results of the free energy variation, it is found that the attractive-repulsive force exists in the case of small particles. As the particle size increases, the force changes from the attractive-repulsive force to the repulsive one. In the attractive-repulsive region, particle distance can be estimated, though the distance estimation is difficult in the repulsive region. Hence, the distance dependency on the particle radius is investigated in the attractive-repulsive region. From the dependency, it is found that the distance is proportional to the square root of the radius. In addition, it is found that the distance is proportional to the fourth power root of the coupling parameter.
