Abstract : The results are presented of thirteen separate observations of the characteristics of the helium nuclei in the primary cosmic radiation. These observations were made using photographic nuclear emulsions flown on high altitude balloons to detect the particles during times ranging from the minimum of solar activity to the maximum. Attention is confined to the presentation of the experimental data, with a detailed discussion of the physical significance being deferred to a later paper. The results are compared with those published previously on the higher charged nuclei in the cosmic radiation. (Author)
