单词	Rydberg atom
释义	Rydberg atom /ˈrɪdbəːɡ / noun Physics An atom in a highly excited state in which one electron has almost sufficient energy to escape. Atoms, usually hydrogen atoms, in this Rydberg state are used in atomic research.Raithel's work suggests that the first few free electrons are not produced by Rydberg atom collisions but when Rydberg atoms are photoionized by black-body radiation.... During the last two years, theoretical studies were performed on a variety of topics related to collisions involving Rydberg atoms. We show that it is possible to excite, and then trap, one and only one Rydberg atom from a cloud of ground state atoms confined on a magnetic atom chip, itself integrated with the Rydberg trap. Origin Named after J. R. Rydberg (see Rydberg constant).
