Abstract
Ionic charge states of anomalous cosmic ray nitrogen, oxygen, and neon with kinetic energies
above 15 MeV /nucleon have been measured using the geomagnetic field as a rigidity filter. Data
from the MAST instrument on the polar-orbiting SAMPEX satellite taken during the period
from 1992 to 1996 show that all three elements are predominantly multiply charged at high
energies, confirming the earlier result for oxygen alone based on a smaller data set. Energy
spectra of the singly charged and multiply charged components of each element are compared
with model predictions.
