A relativistic density-dependent interaction has been used to study hypernucleus ¹⁶O. The density-dependent coupling constants of the relativistic effective Hartree-Lagrangian are obtained from the relativistic Brueckner-Bethe-Goldstone results of nuclear matter in the chiral-σmodel. With these density-dependent coupling constants, the bound states and the single-particle energy spectra of the hypernuclei $_{Λ}^{16} O$ and $_{Σ}^{16} O$ are obtained. The theoretical results of $_{Λ}^{16} O$ are in agreement with the experimental data fairly well.
