On increasing the accuracy of hadron-nucleus interaction characteristics measured by an ionization calorimeter at energies ≥ 1.0 TeV

A technique of correct determination of the first hadron interaction which initiates nuclear-electromagnetic cascade in a calorimeter substance (Fe) is reported. A method of nuclear-cascade curve reduction by means of interpolation of experimentally observed descerete points of the energy absorption function is suggested. The method allows to increase essentially the accuracy of measurement of such nuclear-electromagnetic cascade characteristics as the total number of relativistic particles, the depth of the first maximum and the centre of gravity
