| Abstract | K pi scattering is studied in 77300 bubble chamber events of K/sup +/p to K/sup +/ pi /sup -/ pi /sup +/p and 18800 events of K/sup +/p to K /sup 0/ pi /sup 0/ pi /sup +/p for beam momenta between 2.5 and 12.7 GeV/c. The onshell moments of the angular distribution and the cross sections for K/sup +/ pi /sup -/ to K/sup +/ pi /sup -/, K/sup +/ pi /sup -/ to K/sup 0/ pi /sup 0/ and K/sup 0/ pi /sup +/ to K/sup 0/ pi /sup +/ are obtained by extrapolation to the pion pole. The same procedure applied to the pi /sup +/p system correctly reproduces the known pi /sup +/p scattering. A K pi phase shift analysis between threshold and 1.1 GeV yields two solutions for the S wave isospin /sup 1///sub 2/ phase shift. (21 refs). |
