Data Base

The data base contains on the order of 30K data points from -p ->-p, +p ->+p and -p ->0n.

Observables

Relations for the observables in terms of amplitudes are given in, for example, Bransden and Moorhouse, The Pion Nucleon System, and G.Hoehler, Pion-Nucleon Scattering, Landolt-Bornstein, Vol. I/9b2.

Partial Wave Amplitudes

The partial wave amplitudes are denoted by L2I,2J with L:angular momentum, I:isospin, and J:total spin.
