G4double G4INCL::CrossSectionsTruncatedMultiPions::elastic	(	Particle const *const	p1,
		Particle const *const	p2
	)

virtual

Elastic particle-particle cross section.

The elastic pi-N cross section is calculated by difference: elastic = total - inelastic(pion production) - delta, but we need to use the unmodified piNToDelta cross section, or else we will violate the cross-section sum.

This modification is only necessary for piN collisions.
