[Ifeffit] Ifeffit Digest, Vol 54, Issue 15

[joshua jason kas]

Hi Eckhard,
Add the following card to your feff.inp file.

FOLP 2 0.8

Our default overlap is not so good for hydrogen, and 0.8 is the 
recommended value given in the documentation. There is some instability in 
the calculation of the densities near the nucleus, which in hydrogen, 
turns out to be comparable to the total density, and gives negative 
densities. I don't know why folp 0.8 helps, but it does.
Cheers,
Josh
