S02

From FEFF

Standard

S02 s02

The S02 card specifies the amplitude reduction factor S^2_0 . If the entry for S^2_0 is less than 0.1, then the value of S^2_0 is estimated from atomic overlap integrals. Experimental values of S^2_0 are typically between 0.8 and 1.0.

Alternatively, you can specify the value of S^2_0 in the HOLE or EDGE card; however, the meaning of the parameters in the ‘feff.inp’ file is more clear if you use the S02 card.
