Polarization Structure in p-p Elastic Scattering

We present here the results of an experiment to study the polarization in $p-p$ 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 $t=-1.8\mathrm{}$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$. At 12.33 GeV/c the data exhibit a double zero near $t=-2.4\mathrm{}$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$ and another relative maximum near $t=-2.9\mathrm{}$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$. The results are discussed in terms of the Chu-Hendry optical model.
