Brillouin- (WKB or quasi-classical) approximation and of the method of 1/N ?expansion for solving various problems in atomic  and nuclear physics. The intent of this book is to help students and investigators in this field to extend their knowledge of these important calculation methods in quantum mechanics. Much material is contained herein that is not to be found elsewhere. WKB approximation, while constituting a fundamental area in atomic physics, has not been the focus of many books. A novel method has been adopted for the presentation of the subject matter, the material is presented as a succession of problems, followed by a detailed way of solving them. The methods introduced are then used to calculate Rydberg states in atomic systems and to evaluate potential barriers and quasistationary states. Finally, adiabatic transition and ionization of quantum systems are covered. 606 $aPhysics 606 $aAtoms 606 $aMathematical physics 606 $aQuantum theory 606 $aMathematical Methods in Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19013 606 $aAtomic, Molecular, Optical and Plasma Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P24009 606 $aMathematical Applications in the Physical Sciences$3https://scigraph.springernature.com/ontologies/product-market-codes/M13120 606 $aQuantum Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19080 610 4$aPhysics. 610 4$aQuantum theory. 610 4$aMathematical physics. 610 4$aMathematical Methods in Physics. 610 4$aAtomic, Molecular, Optical and Plasma Physics. 610 4$aMathematical Applications in the Physical Sciences. 610 4$aQuantum Physics. 615 0$aPhysics. 615 0$aAtoms. 615 0$aMathematical physics. 615 0$aQuantum theory. 615 14$aMathematical Methods in Physics. 615 24$aAtomic, Molecular, Optical and Plasma Physics. 615 24$aMathematical Applications in the Physical Sciences. 615 24$aQuantum Physics. 676 $a530.15 700 $aKarnakov$b Boris Mikhailovich$4aut$4http://id.loc.gov/vocabulary/relators/aut$0732531 702 $aKrainov$b Vladimir Pavlovich$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910437983303321 996 $aWKB Approximation in Atomic Physics$91916505 997 $aUNINA
