内容記述 |
An angular correlation function (ACF) of a pair of Lyman-α photons produced in photodissocia- tion of H2 with linearly polarized incident light is measured on a whole sphere at a 33.66-eV photon energy so that we may distinctly substantiate that the 2p atom pairs are in the state previously identified by Torizuka et al. as the 2p atom-pair state [Phys. Rev. A 99, 063426 (2019)], who measured the ACF only on a circle in the plane perpendicular to the incident light beam. The 2p atom-pair state determined with much less uncertainty than before is investigated in terms of whether or not the state is entangled. We discover that the pair of fragment H(2p) atoms is certainly entangled in terms of the electron-electron entanglement, and obtain the entanglement entropy of the 2p atom-pair state. The similar discussion is made in terms of the electronic spatial-spin en- tanglement too, where the spatial motion and spin motion of electrons are considered non-identical partial systems at variance with the former electron-electron entanglement. It turns out that the pair of fragment H(2p) atoms is entangled in terms of the electronic spatial-spin entanglement as well as the electron-electron entanglement. |
