Total Inelastic Scattering Cross Sections Research Articles

Scattering of 190-Mev Deuterons on Protons

A measurement of the total $d\ensuremath{-}p$ scattering cross section is reported. Because of the divergence of Coulomb scattering at small angles, a small angle cutoff has been applied to the elastic scattering. The result may be stated as follows: The cross section for elastic scattering to angles greater than 10 degrees in the c.m. system, plus the total inelastic scattering cross section, is (${94}_{\ensuremath{-}5}^{+7}$)\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}27}$ ${\mathrm{cm}}^{2}$.Measurements are also reported of those inelastic scattering processes in which both protons suffer significant momentum changes. We have termed these events "inelastic $p\ensuremath{-}p$ type collisions." The differential cross sections for these events appear to be smaller than would be expected in view of the theoretical considerations of others.
