Proton-Proton Elastic Scattering from 30 to 250 GeV/c

We present measurements of the proton-proton elastic differential cross section for $1.0<\mathrm{}\left|t\right|<2.0\mathrm{}$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$ and incident proton momenta between 30 and 250 GeV/c. The minimum in the cross section near $t\simeq -1.5\mathrm{}$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$ develops monotonically with increasing incident proton momentum and the cross section remains nonzero up to our highest incident momentum of 250 GeV/c. The cross section at the second maximum near $t\simeq -1.8\mathrm{}$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$ falls with increasing incident momentum up to 210 GeV/c after which it starts to rise.
