Re: [Ifeffit] Postdoc Position

2016-07-29 Thread Bruce Ravel



Jeff (and anyone else who might have a position to offer),

We don't really have rules, per se, just whatever the moderators (Me and 
Matt) are willing to put up with.


I think that helping young scientists find positions in science is a 
superb use of the mailing list.  Those jobs should probably be 
synchrotron-related.  They should probably be spectroscopy-related.

Hi All,

I never remember what the rules are here for posting postdoc positions but I 
have one position available.

Please let anyone who might be interested know.

Thanks,

Re: [Ifeffit] Multiple scattering path parameters

Are there standard ways of relating the parameters (deltaR and sigma^2)
of multiple scattering paths to the parameters of the single scattering
paths based on the type of MS path? For example, would deltaR_MS =
deltaR_SS*2 if the MS was a “forward through” geometry? What about other
geometries and paths that involve different types of atoms?



Scott basically answered your question, but there are a couple relevant 
links in TFM, which you should definitely R:


http://bruceravel.github.io/demeter/documents/Artemis/extended/delr.html
http://bruceravel.github.io/demeter/documents/Artemis/extended/ss.html

Check out the paper by Hudson et al mentioned in section 15.4.2.

I say a few possibly useful things in

https://speakerdeck.com/bruceravel/discussion-of-the-fes2-exafs-analysis-example

A bit of searching in the literature will turn up several papers in 
which people have attempted to quantify the perpendicular contribution 
to Delta R and sigma^2 in the case of collinear MS paths.
