Abstract Within thunderstorms electrons can gain energies of up to hundred(s) of MeV. These electrons can create X-rays and gamma-rays as Bremsstrahlung when they collide with air molecules. Here we calculate the distribution of angles between incident electrons and emitted photons as a function of electron and photon energy. We derive these doubly differential cross-sections by integrating analytically over the triply differential cross-sections derived by Bethe and Heitler; this is… Expand

The importance of electron-electron bremsstrahlung for terrestrial gamma-ray flashes, electron beams and electron-positron beams
Thunderstorms emit terrestrial gamma-ray flashes with photon energies of up to tens of MeV and electron-positron beams that are created by photons with energies above 1.022 MeV. These photons are… Expand
Energy resolved positron and hadron spectrum produced by a negative stepped lightning leader
Gamma-ray flashes with quantum energies up to 40 MeV and beams of electrons and positrons have been detected by satellites above thunderclouds. We here adopt the model of an upward moving negative… Expand
Calculation of beams of positrons, neutrons and protons associated with terrestrial gamma-ray flashes
Positron beams have been observed by the Fermi satellite to be correlated with lightning leaders, and neutron emissions have been attributed to lightning and to laboratory sparks as well. Here we… Expand
Production mechanisms of leptons, photons, and hadrons and their possible feedback close to lightning leaders
TLDR
The feedback mechanism together with the field enhancement by lightning leaders yields particle energies even above 40 MeV measurable at satellite altitudes, because of their high rest mass hadrons are measurable on a longer time scale than leptons and photons. Expand
The structure of ionization showers in air generated by electrons with 1 MeV energy or less
Ionization showers are created in the Earth's atmosphere by cosmic particles or by run-away electrons from pulsed discharges or by the decay of radioactive elements like radon and krypton. These… Expand

A reformulation of the relativistic bremsstrahlung code of Tseng and Pratt is reported, again utilizing partial-wave and multipole expansions in a screened potential within the independent particle approximation, but differently organizing their summation. Expand

TLDR
It is determined that the TGF emission above 10 MeV has a significant power-law spectral component reaching energies up to 100 MeV, and these results challenge TGF theoretical models based on runaway electron acceleration. Expand
