Gamma-Ray Flashes and Neutron Pulses Produced by Gigantic Upward Atmospheric Discharges

摘要：

Gamma-ray pulses are calculated from 2D numerical simulations of upward atmospheric discharge in selfconsistent electric field using multi-group approach to the kinetics of relativistic runaway electrons. Calculated numbers and spectra of gamma-rays are consistent with the data on terrestrial gamma-ray flashes observed from artificial satellites. The calculated runaway electron flux is concentrated mainly within the domain of the Blue Jet fluorescence. This proves that exactly this domain is a source of the flashes. One gamma-ray flash generates ～10 14 - 10 15 photonuclear neutrons.
