A researcher is investigating a cubic crystal with x rays. He is looking at Bragg reflection from the planes parallel to the cube faces. He finds that when using x rays of 0.165 nm a strong first maximum occurs when the beam makes an angle of 23.5° with the planes. What is the spacing of adjacent atoms in the crystal?
