Abstract

The Balloon Borne Experiment with a Superconducting Solenoid Spectrometer (BESS) was flown annually in 1993, 1994, and 1995. In this report we present the energy spectra and isotopic composition of cosmic ray H and He measured from the 1993 flight. The low energy fluxes of H and He agree with the IMP-8 satellite data for a 26 day period (7/14/93 - 8/9/93) that overlapped the BESS flight. Both 2H and 3He were well separated from 1H and 4He. The measured spectra were corrected for the atmospheric overburden and compared with the interstellar/heliospheric propagation calculations.
