The AMADEUS collaboration is investigating the low-energy antikaon interactions with nucleons and nuclei, taking advantage of the lowmomentum antikaons beam provided by the DAΦNE collider at LNF-INFN.
In this work a novel technique is outlined for the measurement of the hyperonnucleon two and three body scattering cross sections. The method consists in producing hyperons by antikaons atomic captures in light nuclear targets, and extrapolating the cross sections from the measurement of the yields of the corresponding elastic final state interactions of the hyperons.
The feasibility of this kind of analyses is shown by comparison of calculated Σ0 production in 4He by K− absorption on three nucleons, with a sample of K−12C absorption measured by AMADEUS in collaboration with KLOE. The feasibility of a dedicated high statistics measurement is discussed.
