Relation between bounceaveraged collisional transport coefficients for geomagnetically trapped electrons
Abstract
The unweighted bounce average (N_{j}) of the atmospheric density N_{j} along a field line and the weighted bounce average < (B_{0}/B) N_{j}cos^{2} α> are related (for each atmospheric constituent j) by an integral or derivative with respect to y, the sine of the equatorial pitch angle α_{0}, where B/B_{0}(=y^{2}sin^{2} α) is the ratio of local to equatorial magnetic field intensity and α is the local pitch angle. The unweighted bounce average <N_{j}> is relevant to energy deposition by radiation belt particles of all species, while the weighted bounce average < (B_{0}/B) N_{j}cos^{2}α> is relevant to the description of pitch angle diffusion of radiation belt electrons.
