FIELD: nondestructive material testing. SUBSTANCE: dependence of current of jump conductance on temperature of sample is found. Sample is exposed to ionization radiation generating electron-hole pairs with subsequent determination of dependence of relaxation of current of jump conductance on time under constant temperature and quasi-equilibrium conditions. Value of energy of activation of jump conductance, degree of compensation and concentration of traps are found by calculation with the aid of obtained dependences. EFFECT: reduced time and improved authenticity of testing. 2 cl, 1 dwg
