摘要：

The AMADEUS experiment at the DA Phi NE collider of LNF-INFN deals with the investigation of the at-rest, or low-momentum, K- interactions in light nuclear targets, with the aim to constrain the low energy QCD models in the strangeness sector. The 0 step of the experiment consisted in the reanalysis of the 2004/2005 KLOE data, exploiting K- absorptions in H, He-4, Be-9 and C-12, leading to the first invariant mass spectroscopic study with very low momentum (about 100 MeV) in-flight K captures. With AMADEUS step 1, a dedicated pure carbon target was implemented in the central region of the KLOE detector, providing a high statistic sample of pure at-rest K nuclear interaction. The first measurement of the non-resonant transition amplitude vertical bar A(K-n -> A pi-)vertical bar at root s = 33 MeV below the (K) over barN threshold is presented, in relation with the Lambda(1405) properties studies.
