Abstract
We present a useful clue to estimate the energy and chemical compositi on of the primary cosmic radiation between 10(14) and 10(17) eV. The m ethod uses various kinds of quantities as measure by a hybrid detector , an emulsion chamber in the central part of an extensive air shower ( EAS) array at mountain altitude. The characteristic features needed fo r the analysis are derived in detail through the Monte Carlo method. T he procedure permits an analysis on individual events; it gives an est imation of the mass and energy of a primary nucleus initiating a showe r. The estimation of the primary energy is with quite negligible ambig uity. We show that the EAS size measurement could be complementary to quantities as measured by an emulsion chamber detector to improve the accuracy of the primary cosmic ray identification.
