摘要

【正】 The mass attenuation coefficients of indium are systematically measured byusing the characteristic X-rays from elemental or compound targets excited by energeticproton in the X-ray energy range 2.6 to 29.1 keV.The accuracy of experimental data isimproved to be±1%.The photoeletric cross sections are obtained by subtracting thescattering cross section from the measured total cross sections.Comparisons of our ex-perimental results with the available data of earlier investigations as well as with thetheoretical calculations are presented and discussed.
