By Dr. Viatcheslav P. Shevelko (auth.)

Atoms and Their Spectroscopic houses has been designed as a reference on atomic constants and easy techniques related to atoms. the subjects comprise strength degrees, Lamb shifts, electrical multipole polarizabilities, oscillator strengths, transition probabilites, and cost move go sections. furthermore the topics of ionization, photoionization, and excitation are mentioned. The booklet additionally contains quite a few figures and tables, with considerable references. basic analytical formulation enable one to estimate the atomic features with no resorting to a computer.

Stretch, Twist, Fold: The Fast Dynamo (Lecture Notes in Physics Monographs)

The learn of planetary or sunlight magnetic fields explains traditional magnetism as a phenomenon of magnetohydrodynamics. The kinematic dynamo concept, specifically the short dynamo taken care of during this quantity, is just a little less complicated yet nonetheless it provides ambitious analytical difficulties with regards to chaotic dynamics, for instance.

Introduction to the Theory of Collisions of Electrons with Atoms and Molecules

An knowing of the collisions among micro debris is of serious significance for the variety of fields belonging to physics, chemistry, astrophysics, biophysics and so on. the current booklet, a idea for electron-atom and molecule collisions is constructed utilizing non-relativistic quantum mechanics in a scientific and lucid demeanour.

Theoretical Atomic Physics

This validated textual content comprises a complicated presentation of quantum mechanics tailored to the necessities of recent atomic physics. The 3rd version extends the profitable moment variation with an in depth therapy of the wave movement of atoms, and it additionally includes an advent to a couple elements of atom optics that are suitable for present and destiny experiments concerning ultra-cold atoms.

The Nuclear Many-Body Problem

This long-standing introductory textual content completely describes nuclear many-body thought, with an emphasis on technique and the technical points of the theories which have been used to explain the nucleus. Now on hand in a more cost-effective softcover variation, the unique contents of "The Nuclear Many-Body challenge” awarded this is meant for college students with easy wisdom of quantum mechanics and a few knowing of nuclear phenomena.

As the starting point for calculations, the central-field approximation is used when each atomic electron is assumed to move in a certain effective central symmetric field Uc(r) of the atomic core created by the nucleus and the other electrons. 19) where Eis the known energy value (experimentally or theoretically).
