New Evidence for Anomalous Cosmic Rays Trapped in the Magnetosphere


We report new observations of ≥ 15 MeV/nuc trapped heavy ions with Z ≥ 2, made on the polar-orbiting SAMPEX spacecraft in late 1992. A trapped population, located primarily near the SAA, includes He, N, O, and Ne. We conclude that they are "anomalous" cosmic rays trapped by the mechanism proposed by Blake and Friesen.
