    "abstract": "We study pairwise entanglements in spin-half and spin-one Heisenberg chains\nwith an open boundary condition, respectively. We find out that the\nground-state and the first-excited-state entanglements are equal for the\nthree-site spin-one chain. When the number of sites L\u003e3, the concurrences and\nnegativities display oscillatory behaviors, and the oscillations of the\nground-state and the first-excited-state entanglements are out of phase or in\nphase.",
