Kaon-nucleon interactions in the T-1 state at 1.6 Gevc incident momentum

A deuterium bubble chamber experiment to investigate the inter-actions of K¯ mesons with neutrons at two incident momenta, 1.45 Gev/C and 1.65 Gev/C, is here reported. Assuming a Hulthen distribution of neutron momentum within the deuteron and using the impulse approximation, an expression is obtained to allow the neutron cross-section to be unfolded from observed effective mass distributions. Energy dependent cross-sections are reported for the principal inelastic channels. In four of these, angular distributions are fitted to Legendre polynomial series, and the coefficients are here reported. A partial wave analysis of the ∧π channel is attempted, and the fits are reported. Evidence is found for the existence of the ∑(2030) and ∑(1910) resonances, but not the proposed ∑(1815) resonance. Values are reported for the parameters of the ∑(2030) and ∑(1910) resonances.
