Query: Dissipation of Hydromagnetic Waves on Energetic Particles: Impact on
  Interstellar Turbulence and Cosmic Ray Transport   The diffusion of galactic cosmic rays (CR) is considered. It is anticipated
that the nonlinear MHD cascade sets the power-law spectrum of turbulence from
the principle scale 100 pc to much smaller scales. We found that the
dissipation of waves due to the resonant interaction with energetic particles
may terminate the cascade at less than 1.e13 cm. The shape of CR diffusion
coefficient that was found may explain the observed peaks of secondary to
primary nuclei ratios at a few GeV/n.
