.... Be aware of spurious peaks such as CukBeta (~0.13% in
a Philips 1050 based system with Graphite monochromator
due to lack of pre-detector slit. Ron Jenkins mention
this at a workshop at AXAA 96 in Sydney)
Be aware of spurious peaks cause by Tungsten satellites.... <<<
Depending on the quality of the sample, these peaks do show up. Its then nice
to have around one, a program like XND that alows these wavelengths to be put
in; I have once had occassion to refine data on a manganese perovskite taken
with primarily CuK\beta radiation using five wavelengths: Cu: K\beta_1,2
K\beta_3 K\alpha_1, K\alpha_2 and W L\alpha_1.
