a New Analysis of Cosmic Ray Isotopes at 3 Gev/n from HEA03-C2 Data
Abstract
Results of mean masses of cosmic rays at energy about 3 GeV/n, for Ne, Al, Mg, Si, S, Ca, and Fe, derived from high energy astronomy observatory 3 data collected by the Danish-French experiment C2 on board (HEAO-3) are presented. A method based upon comparison between observed transmission function and a predicted one computed from a geomagnetic field model was used. Enhancement factors of 2.9 + or - .7 for 22Ne/20Ne, 2.1 + or - .4 for (25Mg+26Mg)/24Mg, and 1.6 + or - .8 for (29Si+30Si)/28Si at GCRS when compared to LG were found.
