Summary:
The complexities of the s-shell ..lambda..-hypernuclei (A less than or equal to 5) are explored. Difficulties associated with attempts to describe the hyperon-nucleon (YN) interaction in all such ..lambda..-hypernuclei by simple, effective ..lambda..p and ..lambda..n potentials are examined. The explicit A dependence of the effective YN interaction due to ..lambda..N-..sigma..N coupling and isospin differences among the nuclear core states is investigated. The necessity of using exact four-body theory to calculate small charge-symmetry-breaking effects (in the A = 4 system) using ..lambda..N potentials fitted to free ..lambda..N scattering data is emphasized. Possible use of s-shell hypernuclear binding energies to help distinguish among candidate YN potential parameterizations is discussed.
