Query: 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.
