[Wien] Effect of Alpha in case.ineece

[Piyush Dua]

Dear Wien users,

I am using PBE-Fock-alpha, in which alpha=0.25 corresponds to PBE0.
If I increase alpha, in certain cases, I use to get better results.
For example the band-gap is better.

I would like to know, upto what limit can one extend the alpha and what will be the physical explanation of increasing alpha?

Thanking you in anticipation.

With regards,

Piyush Dua
