Re: [Ifeffit] how to reduce the core-hole lifetime broadening in feff8.2

Hi Tony, Following Bruce's suggestion, you can reduce the core-hole broadening by making Vi negative. When you do this, note that the amount of reduction is limited by the core-hole broadening (i.e., the variable Gam_ch which is printed out in the header to xmu.dat or chi.dat). Thus for a typical case (Al) where Gam_ch=3.763E-01, you can set Vi= -0.018 in the EXCHANGE or CORRECTIONS cardds. J. Rehr On Thu, 11 Jun 2009, tony vitova wrote:
