摘要：

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