Description
Presentation of the central ΛN-potential bearing both spin and charge dependence is based on the analysis of the basic hypernuclear data (Λp-scattering, bonding energy of hypernuclei basic and excited states). The lightest-weight hypernuclei (λ3 H, λ4 H and λ4 He) were calculated as systems of three or four particles on the ground of high-efficient variation method. More weighty hypernuclei are studied in terms of the two-body model (Λ + undistorted nucleonic core) corrected due to comparison with direct 3-5-particle calculations. Comparison of the calculation results for single and binary Λ-hypernuclei enables to estimate bonding energy of charmed and other (b- and t-quark) super-nuclei if the meson theory considerations are taken into account
