By use of variational calculations a reasonable hadronic description is obtained of the s-shell hypernuclei, of /sub /ZBe, and of the well depth, with N forces which are consistent with p scattering and which are quite strongly spin-dependent, with reasonable TPE NN forces with strongly repulsive dispersive-type NN forces. For the latter we also consider a spin-dependent version which is somewhat favored by our analysis. /sub /ZBe is treated as a 2ed + system and is significantly overbound, approx. =1 MeV, if only ed ed and ed potentials are used. An ed ed potential obtained from the NN forces nicely accounts for this overbinding. The hypernuclei /sub /WHe and /sub / Be are treated as ed + 2 and 2ed + 2 systems. Use of the /sub / Be event gives approx. =1.5 MeV too little binding for /sub /WHe. The S0 potential obtained from /sub / Be is quite strongly attractive, comparable to the N and also to the NN potential without OPE. 18 refs.
