Abstract

A method for measurement of energy of high-energy particles by a thin calorimeter, is presented. The method is based on the correlation analysis of dependence of number of secondary particles, $N_e$, at observation level and the relation of number of particles, $dN$, at two levels, divided by an absorber layer. It is shown, that use of correlation curves ($log N_e$ versus $dN$) allows to reduce essentially errors of definition of energy of the primary particle, which are connected with uncertainty of a primary nucleus and with fluctuations in development of cascade process.
