CasidaMomentumTransfer
CasidaMomentumTransfer
Section Linear Response::Casida
Type block
Default 0
Momentum-transfer vector for the calculation of the dynamic structure
factor. When this variable is set, the transition rates are determined
using an exponential operator instead of the normal dipole one.
