The Balmer-Like Formula for Mass Distribution of Elementary Particle   Resonances
  Elementary particle resonances have been systematically analysed using all available experimental data. We have come to the conclusion that the resonance decay prodact momenta and masses of resonances are to be quantized. The Balmer- like formula for masses of elementary particle resonances was obtained. These observations allow us to formulate a strategy of experimental searches for new resonances and systematize the known one.
