Thank you so much
I got the answer.

Hi Hajar,
The edge energies are ~800% different, and the magic angles will also be ~800%
different. It will be completely impossible to have both edges within magic
angle in the same experiment. Although that is likely a theoretical problem,
as I don't think people usually measure EELS up to 10,000 eV. That's more
X-ray regime. (There is also a so-called "magic angle" in x-ray absorption
spectroscopy, but it's something completely different from the magic angle in
EELS.)
I highly recommend the Hebert paper (2006). The Sun and Yuan paper is also
good but (my memory may be wrong on this) it may contain a mistake in some of
the algebra, whereas the Hebert paper is definitely relativistically correct.
Cheers
Kevin

Dear Kevin
Thank you for your reply
For example, the energy loss of K- and L-edge of a Zn atom in ZnS are 9670 and
1043 eV, respectively.Can one expect the magic angle for K- and L-edge belonged
to a Zn atom to be the same?

It's a function of the energy loss. If the L and K edge belong to different
elements and are at approximately the same energy loss, then they will have
approximately the same magic angle.

dear Gerhard
My mean of magic angle is a collection semi-angle in the ELNES spectrum that
gives rise to the orientation-independent spectrum.

what do you mean with "magic angle" ?
Do you mean the angle where the second Legendre polynonial vanishes ?

Betreff: [Wien] Magic angle for different edges in a sample
Hi dear wien2k developers
I have a question about the magic angle:
Are the magic angles for K-edge and L-edge equal together or are different, in
a sample?
