The total π-mesonic decay rate is found to be 101% of the free Λ decay rate, which is close to the experimental data. Together with the nonmesonic decay the total lifetime of Λ3H is predicted to be 2.56 × 10-10 sec which is 3% smaller than for the free Λ particle. The differential decay rate is evaluated as a function of the pion momentum. The decay into the N+d+π channel is stronger than in the 3N+π channel in contrast to the situation for the nonmesonic decay. The ratio for the decay rate into 3He + π- to the decay rate into all channels including π- is found to be 0.379, which is close to the experimental value. We visualize the decay into the dominant channel p+d+π- in a Dalitz plot. Finally we compare the polarization of the outgoing proton in free unpolarized Λ decay to the polarization of 3He in unpolarized Λ3H decay and we compare the closely related asymmetry of π- emitted parallel and antiparallel with respect to the spin direction for a polarized Λ to the corresponding asymmetry for a polarized Λ3H.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal
