We present results of a K − d experiment performed with the 81 cm Saclay deuterium bubble chamber which was exposed to a K − beam at 4 momenta between 680 and 840 MeV/ c at the CERN PS. Cross sections were measured for inelastic two- and three-body K − n reactions on the basis of 5200 events/mb. Resonance production in the three-body reactions is discussed. In addition, differential cross sections and polarisations are presented for inelastic two-body reactions.

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

Nucl.Phys.B 104 (1976) 382-396, 1976.
Inspire Record 113111 DOI 10.17182/hepdata.35988

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.

MEASUREMENTS OF THE REACTION K- N ---> PI- LAMBDA IN THE C.M.S. ENERGY RANGE 1750-MEV TO 2000-MeV

Corden, M.J. ; Cox, G.F. ; Dartnell, A. ; et al.
Nucl.Phys.B 153 (1979) 485-492, 1979.
Inspire Record 146576 DOI 10.17182/hepdata.34783

The angular distribution and polarization for the reaction K − n→ π − Λ have been measured in the c.m.s. energy range 1750 MeV to 2000 MeV by means of a bubble chamber experiment, producing on average 500 events of this type per 10 MeV energy interval. The data are compared with the predictions of a recent partial-wave analysis of this reaction.
