MEASUREMENT OF THE MASS ATTENUATION COEFFICIENTS FOR SiH4 ANDSi
Acta Physica Sinica, 1995 With X-rays produced by protons exciting elemental and compound targets the mass attenuation coefficients have been systematicaJly measured for SiH4 in the range of X-ray energy 1.486-15.165keV, for Si in 8.041-29.109keV. Not only the validity of Bragg's additivity law in the gaseous compound was verifed by experiment, but also the mass attenuation ...
