We briefly describe our recent Monte Carlo calculations of the energy and angular distributions of neutrons escaping from the solar atmosphere. Comparing the calculation results with measurements of the neutron flux from the flares, we determined the angular distribution and energy spectrum of the a

β¦ Synopsis
It has previously been suggested that the energy for the optical emission of solar flares was provided by ionization losses of accelerated particles in the flares. We show that nuclear interaction of these particles would also produce fluxes of secondary neutrons and gamma rays detectable at the earth. A comparison of the expected intensities of these secondaries with the present upper limit intensities during solar flares shows that such an origin from the optical emission energy is consistent with the measured limits.

We have derived the energy spectrum of accelerated protons and nuclei at the site of the June 21, 1980 limb flare by a new technique, using observations of the time-dependent flux of highenergy neutrons at the Earth. We find that this energy spectrum is very similar to the energy spectra of 7 disk f
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/~ = 8np/B~, where p is the pressure of hot plasma and energetic particles and Bo is the magnetic field in a flaring loop. If/3 ~ 1, t
