The unweighted bounce average (N/sub j/) of the atmospheric density N/sub j/ along a field line and the weighted bounce average < (B/sub 0//B) N/sub j/ cos/sup 2/ ..cap alpha..> are related (for each atmospheric constituent j) by an integral or derivative with respect to y, the sine of the equatorial pitch angle ..cap alpha../sub 0/, where B/B/sub 0/(=y/sup -2/ sin/sup 2/ ..cap alpha..) is the ratio of local to equatorial magnetic field intensity and ..cap alpha.. is the local pitch angle. The unweighted bounce average is relevant to energy deposition by radiation belt particles of all species, while the weighted bounce average < (B/sub 0//B) N/sub j/ cos/sup 2/..cap alpha..> is relevant to the description of pitch angle diffusion of radiation belt electrons.
