Effect of parallel electric field and geomagnetic field distortion on precipitation of charged particles into the lower ionosphere

Abstract

Mead axisymmetric distortions in the geomagnetic field and uniform electrostatic field parallel to geomagnetic field have been assumed to derive an expression for the inhomogeneity parameter, αd. Consequent change in the pitch angle diffusion of charged particles has been obtained. Using these parameters, the variations in the precipitating electron influx with varying stand-off distances and parallel electrostatic fields have been computed. © 1984 Indian Academy of Sciences.
