Aa. Gusev et al., ENERGETIC-POSITRON POPULATION IN THE INNER ZONE, Nuovo cimento della Societa italiana di fisica. C, Geophysics and space physics, 19(4), 1996, pp. 461-467
The possibility of the existence of a natural positron belt in the Ear
th's magnetosphere is considered. It is suggested that the positrons c
an be produced in the nuclear reactions of trapped relativistic proton
s of the inner zone with the residual atmosphere. The positron spectru
m in the range of 10-100 MeV at the top of L = 1.2 is calculated and c
ompared with the experimental results.
