Polarization And Correlation Phenomena In Atomic Collisions: A Practical Theory Course (physics Of Atoms And Molecules)

Polarization And Correlation Phenomena In Atomic Collisions: A Practical Theory Course Bridges The Gap Between Traditional Courses In Quantum Mechanics And Practical Investigations. The Authors Goal Is To Guide Students In Training Their Ability To Perform Theoretical Calculations Of Polarization And Correlation Characteristics In Atomic Collisions. The Book Provides A Concise Description Of The Density Matrix And Statistical Tensor Formalism And Presents A General Approach To The Description Of Angular Correlation And Polarization Phenomena. It Illustrate An Application Of The Angular Momentum Technique To A Broad Variety Of Atomic Processes. This Textbook Contains Derivations Of The Most Important Expressions For Observable Quantities In Electron-atom And Ion-atom Scattering, Including That For Polarized Beams And/or Polarized Targets, In Photo-induced Processes, Autoionization, And Cascades Of Atomic Transitions. Spin-polarization And Angular Distributions Of The Reaction Products Are Described, Including The Angular Correlations In Different Types Of Coincidence Measurements. The Considered Processes Exemplify The General Approach And The Number Of Examples Can Be Easily Extended By The Reader. The Book Supplies Researchers, Both Theoreticians And Experimentalists, With A Collection Of Helpful Formulae And Tables, And Serves As An Excellent Reference.--jacket.
