Hi Riti,

Hi Matt, I have a question about FEFF and I hope you can shed some light on it. Several references point to the high muffin tin radius of H (0.77) in FEFF and say that it should be closer to 0.2. Is there a way of changing the MT radius of H in FEFF? Thank you, -Riti
I'm CCing this to the Ifeffit mailing list, because there are probably many people with more experience with this than me. I believe there is not a simple way to set the muffin tin radius for H or other atoms. But, I think you can tweak this with the "FOLP" setting (usually a number between 1 and 1.25 or so, representing the amount of overlap between atoms). My understanding is that Feff 9 handles hydrogen better than earlier versions, but I don't run very many calculations with H in the structures. Hopefully someone who does will share some insight. --Matt
