Investigations of the dynamics of photodetachment can provide useful insight to the general problem of correlated motions of electrons in atomic systems. The recent development of the Many-Body Theory approach, namely the method based on Random-Phase approximation and Dyson equation, is reviewed in the book. The case of study on photodetachment with emphasis on resonant features for a series of negative ions and the newest data on inner-shell photodetachment are presented. The results of the concrete calculations for the very sensitive to proper account of the many-electron correlations open-shell negative ions are compared with the available experimental data. The objects chosen present the wide range of the resonance types - strong near-threshold and window resonances, interference and autodetachment resonances, shape and Feschbach resonances - and give the most telling example of importance of the collective effects. With using the Feynman diagram technique the physical meaning of the considered effects becomes especially evident.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659769177\"\u003e\u003ch3\u003eMany-Body Theory\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659769177","offer_id":39450474119261,"sku":"9783659769177","price":23.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/9a83658e-ef0d-4cae-9195-5ebf4a62b284.jpg?v=1778135326","url":"https:\/\/shop.autorenwelt.de\/products\/collective-effects-in-negative-ion-photodetachment-many-body-theory-von-galina-schrange-kashenock","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
