We observed a distinct peak in the $$Lambda p$$ invariant mass spectrum of $$^{3}{rm He}(K^-, , Lambda p)n$$, well below $$m_K + 2m_p$$, $$i.e.$$, the mass threshold of the $$K^-$$ to be bound to two protons. By selecting a relatively large momentum-transfer region $$q = 350 sim650$$ MeV/$$c$$, one can clearly separate the peak from the quasi-free process,$$overline{K}N rightarrow overline{K}N$$ followed by the non-resonant absorption by the non-resonant absorption by the two spectator-nucleons $$overline{K}NN rightarrow Lambda N$$. We found that the simplest fit to the observed peak gives us a Breit-Wignerpole position at $$B_{rm {it Kpp}} = 47 pm 3 , (stat.) ,^{+3}_{-6},(sys.)$$ MeV having a width $$Gamma_{rm {it Kpp}} = 115 pm 7 , (stat.),^{+10}_{-20} ,(sys.)$$ MeV, and the $$S$$-wave Gaussian reaction form-factor parameter $$Q_{rm {it Kpp}} = 381 pm 14 , (stat.),^{+57}_{-0} ,(sys.)$$MeV/$$c$$, as a new form of the nuclear bound system with strangeness -"$$K^-pp$$".
