WebJul 10, 2024 · The average intensity should halve if the light let through the slit is halved. Calculated intensity does this because the diffraction pattern begins to lie "off of the screen" (that is, the diffraction pattern is still going at theta=pi/2). Obviously, edge effects of the slit are becoming important for very thin slits. WebMeanwhile, there are the diffraction peaks of quartz (SiO2, No. of JCPDS: 98-000-0369) and mullite (Al4+2xSi2-2xO10-x(x~0.4), No. of JCPDS:98-000-0319) in XRD patterns of specimens after exposure to 850℃ and 1200℃, but their diffraction intensity of peaks significantly weaken.
