LINDEMANN COEFFICIENT OF THE TWO-DIMENSIONAL COLLINS MODEL SYSTEM HAVING LENNARDJONES POTENTIAL

We introduced the Lennard-Jones potential into the two-dimensional Collins model system. The additional potential energy has been derived for two-dimensional solid. According to the classical statistics, the Lindemann coefficient δ_c of this system is calculated along the melting line. The calculated results shows that the value of δ_c approximates to 0.08, which is in agreement with one of the rare gas solids in the order of magnitude.
