a Measurement of the Cosmic Ray Energy Spectra of the Elements Boron to Iron in the Intermediate Energy Region 0.5-2.0 Gev/amu.
Abstract
A description will be given of a cosmic ray experiment designed to measure the elemental abundances boron through nickel in the energy region 0.5-2.0 GeV/amu. Specifically, the energy spectra of the elements B, C, N, O, Ne, Mg, Si, and Fe will be presented. In addition, the cosmic ray abundance ratios relative to oxygen will be given as well as the two abundance ratios B/C and Si/Fe. The measured relative cosmic ray abundances are used in the study of cosmic ray propagation in the galaxy. The predictions of cosmic ray propagation models have been compared to a comprehensive set of cosmic ray abundance measurements which will now include this work. Our relative cosmic ray abundances were found to be in general agreement with other observations made in this energy region. Also, some of the data analysis techniques developed for this experiment have been applied to the Heavy Nuclei Experiment on HEAO-3 and to a Japanese American Cooperative Emulsion Experiment known as JACEE-3. We will present the results of these two computational efforts.
