Proton-Proton Elastic Scattering at 15, 20 AND 30 BeV/c

Abstract

Proton-proton elastic scattering has been measured at 15.2, 20.0, and 29.7 BeV/c. The data at 20.0 BeV/c confirm the presence of a break at $-t\cong 1.2$ ${(\mathrm{B}\mathrm{e}\mathrm{V}/\mathit{c})}^2$. The data at 29.7 BeV/c show essentially the same behavior. The cross section is still falling with increasing energy in this $-t$ range.
