The ^7Li/^6Li ratio in the energy range from 150 to 1300 MeV/nucleon Measured with the balloon-borne ISOMAX 98 instrument in the upper atmosphere
Abstract
We report on the measured ^7Li/^6Li ratio at an atmospheric depth of 4.6 g/cm^2 in the energy range from 183 to 1314 MeV/nucleon, using the Isotope Magnet Experiment (ISOMAX). This balloon-borne magnetic spectrometer in combination with a Time-of-Flight system (TOF) and a silica-aerogel Cherenkov detector was built to measure the isotopic composition of the light elements (3 ≤ Z ≤ 8) in the cosmic radiation up to several GeV/nucleon. ISOMAX was flown on August 4-5, 1998, from Lynn Lake, Manitoba, Canada. The data was collected during 13 hours at an altitude which corresponds to a residual atmosphere of less than 5 g/cm2 . The results on 10 Be/9 Be ratio are presented in the these proceedings by Hams et al. (2001) in the TOF regime and by de Nolfo et al. (2001) in the Cherenkov regime.
