Abstract

The total-cross-section difference in pure longitudinal spin states for $p\ensuremath{-}d$ interactions has been measured at momenta from 1.1 to 6 GeV/c. Spin-dependent Glauber-type corrections and other corrections have been made to obtain $\ensuremath{\Delta}{\ensuremath{\sigma}}_{L}(\mathrm{pn})$ and $\ensuremath{\Delta}{\ensuremath{\sigma}}_{L}(I=0)$. These measurements are of fundamental interest and will also help in determining the existence and nature of dibaryon resonances.
