Dear all, I came across the same type of question concerned with 200 reflection of simple cubic structure at https://www.physicsforums.com/showthread.php?t=465354. Since 220 is a second order diffraction of (110) plane it means there is no need for a (220) plane; like a harmonic in waves. So...

Dear xrd experts, I need help in explaining the diffraction pattern of bcc structure. Specifically, (220) is listed among the planes that give constructive interference since (h2 + k2 + l2) = 8; (h+k+l) = even number. But I am blind to see a single atom on a (220) planes in bcc structure...
