| 书目名称 | Local Density Approximations in Quantum Chemistry and Solid State Physics | | 编辑 | Jens Peder Dahl,John Avery | | 视频video | http://file.papertrans.cn/588/587612/587612.mp4 | | 图书封面 |  | | 描述 | The· simplest picture of an atom, a molecule or a solid is the picture of its distribution of charge. It is obtained by specifying the positions of the atomic nuclei and by showing how the density, p(E), of the electronic charge-cloud varies from place to place. A much more detailed picture is provided by the many-electron wavefunction. This quantity shows not only the arrangement of the electrons with respect to the nuclei, but also the arrangement of the electrons with respect to each other, and it allows the evaluation of the total energy and other properties. The many-electron wavefunction is in principle obtained by solving the many-electron Schrodinger equation for the motion of the interacting electrons under the influ ence of the nuclei, but in practice the equation is unsolvable, and it is necessary to proceed by methods of approximation. Needless to say, .such methods will as a rule depend on the complexity of the system considered. | | 出版日期 | Book 1984 | | 关键词 | Energie; chemistry; distribution; electrons; spectroscopy; spin | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4899-2142-0 | | isbn_softcover | 978-1-4899-2144-4 | | isbn_ebook | 978-1-4899-2142-0 | | copyright | Springer Science+Business Media New York 1984 |
