Abstract
We show that the peripheral part of the elastic scattering impulse approximation can be expressed entirely in terms of on-shell information. The impulse approximation is given in terms of an integral over the onshell elementary amplitude. We find the range of energies required in that amplitude for the peripheral part and discuss the closure approximation to this integral.Keywords
