Our analis is also true for any system which include one charge and one neutral particle with finite size e.g. $π^0μ^{\pm}$-bound states.We consider also cylindrically symmetric bound states and resonances of particles with anomalous magnetic moments.pages 11,LaTeX fileHigh Energy Physics - Phenomenologytext
