Isospin dependence of pion absorption on /sup 3/He

Journal Article · · Phys. Rev. Lett.; (United States)
It is shown that the strong isospin dependence observed in pion absorption on /sup 3/He can be described by the two-body mechanism ..pi..NNarrow-right-left..delta..Narrow-right-leftNN. The effect of the three-body mechanism is also calculated but found to be negligibly small. The ..delta..Narrow-right-leftNN dynamics consistently determined from NN inelasticities is shown to be essential to understand the isospin dependence.
