Abstract：
The Hartree-Fock method is used to calculate the binding energy of Λ hypernuclei ⁵ _ΛHe and ⁹ _ΛBe and the binding energy of charmed Λ(Λ _c) nuclei ⁵ _ΛHe and ⁹ _ΛBe. By setting the ratio of the binding energy of Λ in ⁵ _ΛHe and ⁹ _ΛBe to be equal to the ratio of the binding energy of Λ _cin ⁵ _ΛHe and ⁹ _ΛBe, the Λ _c-N interaction is determined to be equal to 4/5 of the Λ-N interaction. With the interaction thus obtained the binding energ of 1p-shell Λ hypernuclei and 1p-shell Λ _cnuclei are calculated.
