Bound states of scalar particles with arbitrary isospin in the field of regular monopoles and dyons

The Klein-Gordon equation for scalar multiplet transforming according to arbitrary presentation of SU(2) gauge group in the field of the Julia-Zee regular solution is considered. Separation of variables in terms of spin spherical harmonics is realized and approximated solutions of radial equation, describing bound states, are obtained. Formula for energy levels of bound states at arbitrary values of isospin is derived. Inaccuracies, made in previously published works, where partial values of isospin were considered, are mentioned
