CasidaKSEnergyWindow
CasidaKSEnergyWindow
Section Linear Response::Casida
Type float
An alternative to CasidaKohnShamStates for specifying which occupied-unoccupied
transitions will be used: all those whose eigenvalue differences are less than this
number will be included. If a value less than 0 is supplied, this criterion will not be used.
