Hi all,

I'm trying to get some linear optic response of silicon using optic.
I get the imaginary part of the dielectric constant increasing around 2.2 eV. I was expecting it to go up around 1.08 where the band gap is. Do you know what is the problem? I'm using rather small k points 12*12*!2. Is this what may be causing the problem?
Thanks.

Jedo
