Measurements of cosmic ray H-2 and He-3 nuclei above 100 MeV/nuc using a balloon borne telescopeA recent measurement of the hydrogen and helium isotopes obtained from a balloon borne experiment flown from Fort Churchill, Canada at an atmospheric depth of 2.9 g/sq cm on 4 July 1977 is reported. Primary spectra of H-2 and He-3 were obtained up to 150 to 300 MeV/nuc, respectively. The helium isotope observations makes it possible to obtain a mutually consistent picture of galactic propagation and solar modulation and gives information on the possible forms of the He-4 source spectrum.
