Elastic, charge-exchange, and totalK−pcross sections in the momentum range 220 to 470 MeV/c

Abstract

An analysis has been made of 64 600 events of the type $K^{-}p\to K^{-}p$ and 22 800 events of the type $K^{-}p\to {\overline{K}}^{0}n$ in the Berkeley 25-in. hydrogen bubble chamber. Differential cross sections have been measured in intervals of 10 MeV/c over the momentum range 220 to 470 MeV/c. Legendre-polynomial fits to the distributions have been made, and the coefficients show structure from the resonant $D$-wave [$\Lambda \mathrm{}\left(1520\right)\mathrm{}$] and background $S$ and $P$ waves. No new structure is observed. The total $K^{-}p$ cross section determined from measurements of all final states seen in this exposure is also presented.
