Electric field excited in air by a pulse of gamma rays
The characteristics of the electric field produced by air polarization during the passage of nonstationary Compton currents excited by a γ-ray pulse in low-density air are discussed. The influence of the field on the motion of the Compton electrons is taken into account. The amplitude and relaxation time of the field are evaluated. A polarization electric field is created through the action of a directed current of γ-rays in air because of the movement of the Compton electrons. This paper discusses the basic characteristics of the resultant field in low-density air. A similar problem was raised in , where the electromagnetic field excited by a nonstationary source of γ-radiation in the upper atmosphere was considered. In that case, the Compton-electron currents were specified and their magnitude was assumed to be proportional to the ratio between the gas kinetic ranges of Compton electron and γ-ray (this ratio is of the order of 0.01 and is indepenent of height). With an increase in electron range, however, the decelerating action of the resultant electric field on the motion of the Compton electron becomes important (eEι/ɛ is a criterion for the effect; E is the field intensity, and ι and ɛ are the range and energy of the Compton electron).
