[Ifeffit] Artemis/FEFF question

Dear All,

The database at http://cars9.uchicago.edu/~newville/adb/search.html is down
and I am trying to create an input file (for feff calculation) for pure
scandium ( http://www.periodni.com/sc.html ).

The problem is when the 'atoms', and 'feff' in Artemis calculate the
scattering paths, they shows distances smaller than the expected 3.256A
nearest neighbor distance. What is the error in the input file attached
below ?

Thank you.
