Abstract: (Springer)

A new procedure for determining the energies of particles of primary cosmic radiation is described. The procedure is based on measuring the spatial density of the flux of secondary particles originating from the first event of nuclear interaction that have traversed a thin-converter layer. The use of the proposed method makes it possible to create equipment of comparatively small mass and high sensitivity. The procedure can be applied in balloon-and satellite-borne cosmic-ray experiments with cosmic nuclei for all types of nuclei over a wide energy range between 1011 and 1016 eV per particle. Physical foundations of the method, results of a simulation, and the applicability range are described.
