Intensity of the corpuscular and the photon component of cosmic radiation at sea level

Abstract

The distribution of cosmic radiation in its relation to the zenitl angle was measured for single shocks in one counter and for two-fold and three-fold coincidences. From the relation of single shocks to two-fold coincidences the amoun of photons could be found and the efficiency of the photons for counters For the unit of opening-angle in a direction δ and on an area of 1 cm 2 a right angles to that direction per minute was found: Corpuscular rays I III = 0,016 + 0,050 cos 2 δ single shocks I I = 0,054 + 0,625 cos 2 δ two-fold coinc. I II = 0,02 + 0,51 cos 2 δ photons I P = 1,17 + 4,027 cos 2 δ (κ=3%) The efficiency λ lies between 3% and 6%. When δ increases from 0 to 90° the number of photons divided by that of corpuscles increases from 10 to 60. The intensity of the rays for all directions is given and compared with those of other authors. We found for single-shock radiation on 1 cm 2 p. min.: 1,14 and for corpuscles 0,82.
