Is revealed with probability not below 0.999999, that masses of heavy elementary particles, including nucleons, are divided on quantums, and they consist more, than on 99.8 % of quantums only 4 kinds with energy, decreasing according to cubic law. The energy of quantum of the first kind (named basic) is equal 43.9912 (22) MeV.

It is proved to that the probability of concurrence of a spectrum of masses of heavy elementary particles   with a spectrum of the casually distributed sizes in the same range, with what revealed algorithm has, is rather small (less by than one million).

The diagram displays definition of a general maximum determining sizes of energy of the basic tract and average additional energy of heavy elementary particles, not entering directly in energy of tracts existence, appropriate to the maximal probability, of the revealed law. On an axis Õ the energy of the basic tracts Ò1 is postponed, on an axis Y the average additional energy S, on an axis Z - probability of existence of the revealed law ð (E), taking into account physical restriction is postponed.
