Description: BEXX specifies the fraction of short-range exact exchange in range-separated hybrid-functionals constructed with LMODELHF=.TRUE.
The BEXX tag specifies the fraction of short-range exact exchange in range-separated hybrid-functionals. This tag can be used only when LMODELHF=.TRUE. More details can be found in the description of this class of hybrid functionals.
