Coulomb energy values of the 1p-shell hypernuclei and charge dependence of ΛN forces

To determine charge dependence of ΛN-nuclear forces calculated are differences of values of binding energies, caused by Coulomb interaction for hypernuclear isobars 7Li-7He, 8Be-8Li, 9Be-9Li, 9Be-9Be, 10B-10Be, 11B-11Be, 11C-11B, 12C-12B, 13C-13B, 13N- 13C, 14N-14C, 15O-15N, 16O-16N. Corrections to differences of Coulomb energy of hypernuclei Δ=ΔBsub(Λ)sup(exp) Δ Bsub(Λ) sup(theor) for hypernuclear pairs: 4H-4He, 8Li-8Be, 9Li-9B, 10Be-10B, 12B-12C, are calculated, they are presented in the table. It is noted that if the difference between ΔBsub(Λ)sup(theor) and ΔBsub(Λ)sup(expl) is not an experiment error, the most probable explanation of this difference is existence of charge dependence of ΛN forces of Mayoran type
