Energy balance of cosmic rays in multiple scattering in a randomly inhomogeneous magnetic field
Dorman L.I., Kats M.E., Fedorov Yu.l., Shakhov B.A.
The equation for the energy density of cosmic rays is used to analyze the variation of their energy following multiple scattering by random magnetic-field inhomogeneities that move with velocity u(r). It is shown that if the radial gradient of the cosmic rays is positive the particles land in the acceleration regime.
