Abstract: It is demonstrated that the coordinates of the fcc-bcc-fluid triple point of various model systems are located in a relatively narrow region, when expressed in terms of the two proper variables, characterizing the softness and strength of the interaction force at the mean interparticle separation. This can be regarded as a consequence of the “corresponding states principle” for strongly interacting particle systems we have put forward recently (K hrapak S. A., C haudhuri M. and M orfill G. E., J. Chem. Phys. , 134 (2011) 241101). The related possibilities to predict the existence and approximate location of the fcc-bcc-fluid triple point for a wide range of pair interactions with variable softness are illustrated. Relation of the obtained results to experimental studies of complex (dusty) plasmas are briefly discussed.
