GENERAL ATOMIC PHYSICS AND ATOMIC PHENOMENA
Prof. Yuri Gangarskii (Flerov Laboratory of Nuclear Reaction)
5th semester, Lectures: 51 hours, Seminars 34 hours
The aim of the course “General atomic physics and atom phenomena” is to study properties of atoms and more complex objects based on the atoms,as well as to gain practical skills for interpretation and use of a wide range of atomic phenomena. Students should get a clear idea of the detailed atomic structure of different elements, interaction between atoms and atoms with external fields, and formation of molecules and complex combinations from atoms. It will enable them, first, to choose the most proper way to decide specified tasks in the field of atomic physics; and, second, to interpret the received resultscorrectly. While giving this course, we assume that students have taken the standard course of higher mathematics (derivative, integral, differential equations) and know the basics of electricity theory.
After having taken this course, a student should:
- get a basic insight into atomic structure and physical systems, which consist of them
- be able to formulate problems in the field of nuclear physics and find ways to solve them
- apply the apparatus of mathematical analysis to the calculation of different atomic processes
- effectively analyse the received results on the basis of different models, which describe behaviour of atomic systems of different nature
- offer solutions to specified application problems, which answer today’s purposes.
