We study the spin-orbit splitting (ls splitting) for the proton d orbits in {sup 23}F in the Hartree-Fock framework with the tensor force in the exchange channel. {sup 23}F has one more proton around the neutron-rich nucleus {sup 22}O. A recent experiment indicates that the ls splitting for the proton d orbits in {sup 23}F is reduced from that in {sup 17}F. Our calculation shows that the ls splitting in {sup 23}F becomes smaller by a few MeV because of the tensor force. This effect comes from the interaction between the valence proton and occupied neutrons in the 0d{sub 5/2} orbit through the tensor force and makes the ls splitting in {sup 23}F close to the experimental data.
