Abstract : The results of two experiments are presented. The experiments add substantial evidence to the belief that heavy relativistic primary cosmic rays of charges equal to or greater than ten are not appreciably affected by solar activities. Nor is the total flux at the top of the atmosphere at a given geomagnetic latitude influenced appreciably by intervening magnetic fields between the earth and the sun or by the magnetic field of the earth. Comparison with neutron intensities were made. Ilford G-5 emulsions were exposed during balloon flights at geomagnetic latitudes of 62 degrees N and 41 degrees N. The first experiment was based on a short, high-activity period of the sun. The second experiment covered eight years at times when no large flares existed. (Author)
