What is Primary Alpha Particles in the Cosmic Radiation Near the Geomagnetic Equator about?
An apparatus consisting of a G-M counter coincidence train in which is interposed a high-pressure ionization chamber has been utilized to obtain measurements of the flux of primary helium nuclei during a series of balloon-flights in India. The instrument records relativistic particles characterized by a specific ionization at least as great as that of an alpha particle. The experiments were conducted at Aligarh, Uttar Pradesh (geomagnetic latitude 18" N) and Bangalore, Mysore (geomagnetic latitude 3" N). At each station, the intensity N(I > 3.2Imin) of particles producing ionization chamber pulses exceeding the bias setting corresponding to 3.2I,i,, plotted on a logarithmic scale as a function of atmospheric depth, follows a straight line. The intensity N,,r was also measured by removing the criterion 1 > 3.2Imin. Taking into account local nuclear interactions initiated by protons, knockon electrons accompanying protons, and slow protons (albedo) which actuate the apparatus, the'alpha-particle flux is determined from the extrapolated values of Nbbr and N(I > 3.2ImiJ at the "top of the atmosphere." The results are: 49 i 13 particles mm2 sec-' sterad-' at X = 3' N, and 81 f 22 partic
