A quasipotential approach to low energy relativistic corrections
A simple phenomenological way of estimating the contribution of crossed- ladder graphs to the magnitude of relativistic corrections in low energy nucleon- nucleon scattering is proposed. The approach is based on the Todorov equation, since it is a simple 2body relativistic wave equation with the right static and eikonal limits. The interaction kernel used is based on the iterated Blankenbecler - Sugar - Logunov- Tavkhelidze equation. Within this model, good agreement is found with some results obtained by Levine and Wright, who include one ladder and one crossed ladder graph in the Bethe - Salpeter equation. For low energy nucleon-nucleon scattering, it is found that the phase shifts differ at most by 20% from those obtained with the LippmannSchwinger equation.
