Scientific paper

It is shown that escaping of solar flare energetic protons into interplanetary space as well as their relation to the flare gamma-ray emission depend on the parameter β = 8πp/B02, where p is the pressure of hot plasma and energetic particles and B0 is the magnetic field in a flaring loop. If β very low 1, the bulk of the energetic protons escape to the loss cone because of diffusion due to small-scale Alfvén-wave turbulence, and precipitate into the footpoints of the flaring loop. The flare then produces intense gamma-ray line emission and a weak flux of high energy protons in interplanetary space. If β > β* ≅ 0.3 - 1.0, then fast eruption of hot plasma and energetic particles out of the flaring loop occurs, this being due to the flute instability or "magnetic-field-plasma" nonequilibrium. The flare then produces a comparatively weak gamma-radiation and rather intense proton fluxes in interplanetary space.
