ISEE-3/ICE High Energy Cosmic Ray Composition Tables


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1978-08-12 to 1981-04-30


The ASCII files in this data set contain tabular summaries of cosmic ray elemental and isotopic composition in interplanetary space at 1 A.U. near Earth as measured by the high energy cosmic ray experiment on ISEE-3/ICE. These measurements cover the time interval from August 1978 to April 1981 and particle nuclei energies in the general range of 50 to 500 MeV/nucleon. The contents of the files are as follows: (1) elemental abundance Ratios in file TABLE1.TXT, isotopic fractions in TABLE2.TXT, and isotopic abundance ratios in TABLE3.TXT. Each file also lists the references in which the measured values were published.
