We perform coupled-cluster calculations of the energies and lifetimes of single-particle states around the doubly magic nucleus ^{16}O based on chiral nucleon-nucleon interactions at next-to-next-to-next-to-leading order. To incorporate effects from the scattering continuum, we solve the coupled-cluster equations with a Gamow-Hartree-Fock basis. Our calculations for the J^{pi} = 1/2^{+} proton-halo state in ^{17}F and the 1/2^{+} state in ^{17}O agree well with experiment, while the calculated spin-orbit splitting between d_{5/2} and d_{3/2} states is too small due to the lack of three-nucleon forces. We find that continuum effects yield a significant amount of additional binding energy for the 1/2^{+} and 3/2^{+} states in ^{17}O and ^{17}F.
