The properties of hypernuclei are studied systematically using a two-dimensional Skyrme–Hartree–Fock approach combined with three different
Skyrme forces fitted to reproduce the existing data. We explore the impurity effect of a single
hyperon on the radii, deformations, and density distributions of the nuclear core and point out qualitative differences between the different forces. We find that the
removal energy of
B [
C(g.s.)+
(1p)] calculated by the SLX3 force is 0.7 MeV, which is in good agreement with a possible value of
MeV from the KEK E176 experiment. The theoretical prediction for this weakly bound state depends strongly on the deformation of the nuclear core, which is analyzed in detail.
