【 摘 要 】

Experiment E906 at the BNL-AGS, searching for light S= -2 hypernuclei, found strong evidence for the nuclide(sub(Lambda)(Lambda))(sup 4)H. Perhaps the most striking feature of this experiment was the presence in the data of a narrow low-momentum(pi)(sup -) line at k(sub(pi))= 104-105 MeV/c. This line was ascribed to the decay of(sub(Lambda)(Lambda))(sup 4)H into a resonant state in(sub(Lambda))(sup 4)H. The existence of such a state is shown to be plausible, its characteristics delineated, and its relevance to ongoing theoretical calculations considered.
