Abstract

We suggest that a dip at

t = - 3

{(G e V / c)}^{2}

which appears in both

π^{+} p

and

π^{-} p

scattering over a wide range of laboratory momentum is related to the dips in the 180-deg cross sections at 2.1 GeV/c. The energy dependence of the cross sections in the vicinity of the dip is consistent with a Regge trajectory for which

α = - 2

t = - 3
