Dear Quirina, The paper by Alexander to which you refer is probably the one in Volume 20 of Advances in X-ray Analysis. I just did a quick search on the new CD ROM from ICDD which has a cumulative index of titles for the entire 1-40 sets plus the actual proceedings for the 1996 'Denver X-ray Conference'. As you may know, the Denver X-ray Conference proceedings are now "published" in CD form ... no paper. I'm not sure I like that, but I accept it like the sunrise or sunset. Good wishes, Ray Young R.
