Abstract : The relative abundances of protons, deuterons and tritons were studied in photographic nuclear emulsions flown during the July 18th, 1961 solar flare event. These emulsions were exposed at a time and locality where there was a geomagnetic threshold and the consequent enrichment of the abundance ratios was used to reduce the abundance limits to lower values than those previously quoted. By including the results of pre vious alpha-particle measurements in these emulsions, the relative abundances of solar produced H1, H2, H3 and He above a given rigidity at this time were determined. The consequences of these observations are briefly discussed. (Author)
