Abstract
The binding-energy data of the -shell hypernuclei and the total cross sections of the -proton scattering are examined with two-body, spin-dependent, charge-independent, central -nucleon potentials which have an intrinsic range of 1.5 F and a hard core with a radius of 0, 0.3, 0.45, or 0.6 F. The main purpose is to see whether there exists a hard core in the -nucleon interaction. The results show that a hard core very likely does exist and has a radius greater than about 0.3 F. Also, it is found that even when the hard-core radius is as large as 0.6 F, the -nucleon interaction is not strong enough to bind together a two-body -hypernuclear system. However, it does seem to be strong enough to allow the formation of a particle-stable excited state in the hypernucleus with a small binding energy.
