  Article:   COMPARISON OF THE POTENTIAL ENERGY FOR SPHERICAL CODES USED IN CW EPR POWDER SIMULATIONS.

Authors:  .
 
       
         
  Abstract:  The uniformity of some spherical codes used for the simulation of CW EPR powder spectra is assessed from the potential energy point of view. The Igloo, SOPHE and EasySpin analytically generated grids and the Repulsion and SCVT irregular spherical codes are compared using the Riesz s-energy and the Korevaar''s modified Coulomb energy, if equal electric charges are placed at the points of the grids. Weighted forms of the energies, based on the areas of the Voronoi cells generated by the points spread on the unit sphere, are compared.

Keywords: CW EPR, simulation, powder spectra, spherical codes, Riesz s-energy
