The distribution of secondary particles in stars produced in annihilation of nucleon-antinucleon pairs is calculated, using the statistical theory of multiple production of particles. Exact expressions for the statistical weights, taking into account conservation of energy, momentum and isotopic spin, were used in the calculations. The calculations were carried out for several magnitudes of the effective volume in which the energy is distributed, and for several types of particles created in the annihilation. The mean multiplicity (3 to 5) of pi mesons obtained theoretically agrees with the available experimental data, whereas the number of K mesons predicted by the theory ls substantially higher than experimentally observed. The momentum distribution of secondary pi mesons in the center-of-mass system is also computed. (auth)
