WebApr 7, 2024 · The procedure is like this - let the point "A" in the diagram denote the origin (000) in reciprocal space. Draw the incoming k-vector with its tip on the point A, as in the diagram.Then draw the sphere of radius k around the tail of this vector.If the sphere intersects any point B = (hkl) in reciprocal space, then the (hkl) planes satisfy the Bragg … In analytic geometry, a line and a sphere can intersect in three ways: 1. No intersection at all 2. Intersection in exactly one point 3. Intersection in two points.
