Abstract

An analytic function of energy is fitted to the available $S$ , $P$ , and $D$ wave $π N$ phase shifts of various goups below 400 MeV. This global average, which reproduces well most of the experiment cross sections, is anticipated to be useful in pion-nucleus and pion-nucleon interaction calculations.

NUCLEAR REACTIONS $π^{\pm} N$ ; 0-400 MeV; analytic function fitted to tabulated phase shifts.
