Nl. Lavrik et Vp. Voloshin, Calculation of mean distances between the randomly distributed particles in the model of points and hard spheres (the method of Voronoi polyhedra), J CHEM PHYS, 114(21), 2001, pp. 9489-9491
The method of Voronoi polyhedra is used to introduce the concept of nth nei
ghbor. For hard spheres a theoretical dependence of the mean distance betwe
en the nth neighbors on the coefficient of filling was obtained. A simple f
ormula was obtained to estimate the mean distance between the nth neighbors
