Polarization Structure in p-p Elastic Scattering

Abstract

We present here the results of an experiment to study the polarization in $p\ensuremath{-}p$ elastic scattering at the incident momenta 5.15, 7.00, and 12.33 Ge V/c, at $t$ values ranging between - 0.5 and - 6.5 ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. At each momentum we observe a relative maximum in the polarization around $t=\ensuremath{-}1.8$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. At 12.33 GeV/c the data exhibit a double zero near $t=\ensuremath{-}2.4$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ and another relative maximum near $t=\ensuremath{-}2.9$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. The results are discussed in terms of the Chu-Hendry optical model.
