We present a microscopic calculation of spectroscopic factors for neutron and proton removal from {sup 24}O using the coupled-cluster method and a state-of-the-art chiral nucleon-nucleon interaction at next-to-next-to-next-to-leading order. To account for the coupling to the scattering continuum we use a Berggren single-particle basis that treats bound, resonant, and continuum states on an equal footing. We report neutron removal spectroscopic factors for the {sup 23}O states J{sup {pi}}=1/2{sup +}, 5/2{sup +}, 3/2{sup -}, and 1/2{sup -} and proton removal spectroscopic factors for the {sup 23}N states 1/2{sup -} and 3/2{sup -}. Our calculations support the accumulated experimental evidence that {sup 24}O is a closed-shell nucleus.
