Özet

The total mass attenuation coefficients (mu(m)) for SiO(2) {Quartz (1 1 0 1), Quartz (1 1 0 0) and Quartz (0 0 0 1)}, KAlSi(3)O(8) {Orthoclase (0 1 0), Orthoclase (1 0 0)}. CaSO(4) center dot 2H(2)O (gypsum), FeS(2) (pyrite) and Mg(2)Si(2)O(6) (pyroxene) natural minerals were measured at 22.1, 25.0, 59.5 and 88.0 keV photon energies. The gamma- and X-rays were counted by a Si(Li) detector with a resolution of 160 eV at 5.9 keV. Atomic and electronic cross sections (sigma(t) and sigma(e)), the effective atomic and electron numbers or electron densities (Z(eff) and N(eff)) were determined using the obtained mu(m) values for investigated samples.
