Hi Jon,
Funny you should mention the background... it was very low, as you say.
Above 30 degrees the background averaged only 2 counts, with a minimum
of 1 count and a maximum of 3 counts, throughout the rest of the
spectrum. Scan time was 2 hours.
I also found that there was some kalpha2 in the spectrum, with Ka2/Ka1 =
0.05.
