The statistical significance of the corresponding peak in lambda p effective mass spectra is defined by more than five standard deviations. Its effective production cross section in n exp 12 C collisions at < P/sub n/ >=7.0 GeV/c is estimated to be sigma/sub pr/ (2256)=(85.3+-20.0) mu b, whereas the effective production cross section in lambda p implies lambda p interactions is sigma/sub pr/(2256) = 5.3(2J/sub lambda p/+1) mb. The lambda p effective mass spectra which have been investigated in this experiment reveal, apart from the well-known approximately(M/sub lambda /+M/sub p/) MeV/c exp 2 and 2128 MeV/c exp 2 peaks, enhancements including 2256 MeV/c exp 2 peak near the most of the resonance mass values predicted by MIT Bag Model. Possible mechanisms of multibaryon resonance formation are discussed. According to the hypercharge selection rule Y <= 1 multibaryon resonances are shown to be ultra-high density superstrange objects. (Atomindex citation 10:468410) 收起
