Abstract

We propose a method to calculate the type of a lattice formed by grains in dusty plasma and estimate its potential energy. Basically, this task is complicated by the interparticle potential that appertains to “catastrophic potentials”. This kind of potentials needs special approaches to avoid divergences during potential energy calculations. In the current contribution, we will develop all the necessary modifications to appropriate methods. It will be shown that the obtained potential energy expression can be used to determine lattice parameters and these parameters comply to known experimental data.
