I assume you mean you "can't assign a [variable] to N."

It's a quirk of FEFF that the value of N for a path must be a number (perhaps even an integer?) but amplitude may be any number or a variable.  For that reason it's typical (or at least common practice in my experience) to leave N as 1 and define the amplitude as some function of So2, degeneracy, percent of that phase, or whatever else is appropriate for your sample.

Hi all,

When I model a standard, I know the degeneracy through the other data. But for spectra of unknown material, I would like to set degeneracy as a variable like the amplitude, deltE0, e.g.. However, I can assign a letter to N and define it. Do you have any idea how I should do it?

Thanks for your reply,

Peng
