Cross Section Calculation Interface.
double XSec(const Interaction *i, KinePhaseSpace_t k) const
Compute the cross section for the input interaction.
bool ValidKinematics(const Interaction *i) const
Is the input kinematical point a physically allowed one?
TSpline3 * fXsplNuebar
a spline around the 16O+nu_e xsec points listed in the reference paper
bool ValidProcess(const Interaction *i) const
Can this cross section algorithm handle the input process?
static const double kMaxE
enum genie::EKinePhaseSpace KinePhaseSpace_t
