“…Such questions as Moser [26] and Kustaanheimo-Stiefel [15] regularization procedures as well as the relationship between them [14] are well known for celestial mechanics specialists. Also the questions concerning the quantization of the Kepler system and the MIC-Kepler system, which is its natural generalization, are the subject of many publications, see, e.g., [8,17,19,24,25,28,31]. There are other interesting generalizations of Kepler and MIC-Kepler problems, for example see [2,11,19,20,21,22].…”
