In a series of COSMOS satellite flights plastic nuclear track detectors
have been exposed in low-earth orbits to monitor anomalous cosmic rays
(ACR) at energies below 25 MeV/nuc.
The analysis of energy spectra has now
been extended to energies up to 40 MeV/nuc for two exposures aboard
COSMOS 2260 in 1993 and COSMOS 2311 in 1995.
Our data on trapped ACR (TACR) oxygen
energy spectra might indicate the influence of energy-dependent stripping
probabilities and the presence of multiply charged ACR oxygen at high
energies as reported by latest SAMPEX observations.
