    "abstract": "An analytic expansion of the exact one-electron momentum density of the\nHooke\u0027s atom is derived for the case k = 1/4. Electron correlation is shown to\nhave opposite effects on the momentum density, compared with the Moshinsky\u0027s\natom, but is qualitatively similar to classical two-electron atomic systems at\nlarge momenta.",
