Dear collegues I have read J. I. Langford's article (J. Appl. Cryst. 2000. 33, 964-974 ) and there I saw the following equation for the line profile (that was obtained from A.J.C. Wilson-1962): I(2theta) = [cos(theta)/lambda] I(s) I would like to know what the exact meaning of the cos(theta) factor in this equation is. What does it describe? I will be very grateful for some help.
Thank you in advance João B S Barbosa National Commission for Nuclear Energy Belo Horizonte- BRAZIL E-mail: [EMAIL PROTECTED]
