Crystal-field calculation program for Eu(3+)

[Vitoria Pablo n-2260 <vpablo $#at#$ nc.titech.ac.jp>]

 Hi.
 I am new to this list.
 I am a PhD student, doing reasearch on Eu(3+) luminescence in crystals.
 Until now, I've been measuring emission and absorption spectra, and
 relating these to the environment of Eu in the crystal.
 To make these correlations more quantitative, I would like to be able
 to calculate crystal-field and Judd-Ofelt parameters from the spectra
 and some crystallographic information. It would be nice also to be able
 to calculate energy-levels of Eu(3+) (splitting of the free-ion J levels,
 shift of the barycenters,...) from structural data of the ligands (mainly
 oxygen in my case) around the Eu(3+) ion; or even to simulate the emission
 or absorption spectra from structural (and other necessary) data.
 Is anybody aware of programs that are able to make these calculations?
 I would like programs for Mac, or Unix workstation, just because I am
 familiar with these computers. But any other would be OK also.
 Any information is appreciated. I would like the answers by e-mail, and not
 to this newsgroup, as I cannot read it so often.
 Thanks a lot for your help.
