Hello again,
I have a question regarding characteristic peaks in a X-ray spectrum.=
A Finnish textbook shows a typical figure on intensity against wavel=
ength with a continuous part and characteristic peaks. There is one p=
eculiarity, however: the intensity of the K(alpha) peak is smaller th=
an K(beta) and K(gamma) peaks. I have thought that the intensity of a=
characteristic peak is related to the probability at which a certain=
transition takes place and that the transition from the L-shell (n =
=3D 2) into the K-shell (n =3D 1) would be more probable than the tra=
nsition, say, from the M-shell (n =3D3).=20
Is it possible that for some elements the K(beta) peak would indeed b=
e greater than the K(alpha) peak? Or is there simply a mistake in the=
textbook?
