New data are presented on the reaction K − n → K ∗− (890) n from a deuterium bubble chamber experiment. An energy-dependent partial-wave analysis from threshold to 2170 MeV c.m. energy is described, in which a new decay mode of the Σ(2030) resonance into K ∗ (890) N in the S = 3 2 state is clearly observed. An amplitude at resonance of 0.12 ± 0.02 is obtained, consistent with the assignment of the Σ (2030) to the same SU(3) decuplet as the Δ(1950).

Measurements of the Reaction K- n --> pi- Lambda in the c.m.s. Energy Range 2050-MeV to 2175-MeV and Partial Wave Analysis of This Reaction Between 1875-MeV and 2175-MeV

Corden, M.J. ; Cox, G.F. ; Dartnell, A. ; et al.
Nucl.Phys.B 104 (1976) 382-396, 1976.

New bubble chamber data on the reaction K − n → π − Λ in the c.m.s. energy range 2050 MeV to 2175 MeV are presented. These new data have been combined with published data on this reaction and on the reaction K − p → π 0 Λ and a partial-wave analysis has been carried out between 1875 MeV and 2175 MeV. Parameters of the established resonances in this c.m.s. energy region have been determined and further evidence is presented for the existence of a Σ resonance with mass around 2100 MeV/ c 2 in the P 3 partial wave.
