Abstract: 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-o model. With these density-dependent coupling constants, the bound states and the single-particle energy spectra of the hypernuclei 16ΛO and 16ΣO are obtained. The theoretical results of 16ΛO are in agreement with the experimental data fairly well.
