YN CORRELATIONS FROM THE STOPPED K− REACTION ON 4He

We have investigated non-mesonic reactions of the stopped K− on 4He in terms of correlations of coincident ΛN pairs. As the result, Λp and Λn branches of the two-nucleon absorption process were clearly observed in the ΛN invariant mass spectra. The spin-isospin dependence of the process was observed for the first time.
