FORMATION OF LAMBDA-LAMBDA-HYPERNUCLEI BY XI- CAPTURE IN LIGHT-NUCLEI

We discuss the production of doubly strange LAMBDA-LAMBDA hypernuclei in XI- atomic capture. The two-body XI- + Li-6 --> LAMBDA-LAMBDA-He-6 + n reaction is a relatively favorable case, with a yield of order 3%. For heavier p-shell targets, such as N-14, the (1s-LAMBDA)2 ground-state yields in the XI- + (A)Z --> LAMBDA-LAMBDA-A(Z-1) + n reaction are suppressed, and states of (1s-LAMBDA-1p-LAMBDA) structure, coupled to an excited nuclear core, are preferentially populated.
