| Popis: |
The ${\ensuremath{\pi}}^{\ensuremath{-}}p$ elastic scattering differential cross section has been obtained at 18 incident momenta from 1.71 to 5.53 GeV/c. The measurements were taken over a limited range of squared four-momentum transfer $t$ near the forward direction. The statistical accuracy and resolution of these data are comparable to, or better than, existing data. The parameter $b$ in the expression $\frac{d\ensuremath{\sigma}}{\mathrm{dt}}=A{e}^{\mathrm{bt}}$ has been determined at each of our incident momenta, and a large (\ensuremath{\sim}25%) enhancement in $b$ as a function of momentum is observed at a c.m. energy of \ensuremath{\sim}2290 MeV. The relation of this bump in $b$ with the well-established bump in the total ${\ensuremath{\pi}}^{\ensuremath{-}}p$ cross section at \ensuremath{\sim}2200 MeV is discussed. |
