|ATOMIC AND NUCLEAR PHYSICS WITH APPLICATIONS||FAF270|
The course is an important part of a larger course package in physics. Based on quantum mechanics, it gives the basis of fundamental atomic and nuclear physics, as well as technical applications, e.g., laser technology and environmental measurement techniques. It gives a broad orientation about microcosm, while at the same time including detailed studies of selected topics. The aim of this is to simultaneously practice quantum mechanical problem solving, and to stimulate the interest for further studies in the subject. By highlighting important technical applications the course aims at illustrating the mutual dependence between technology and basic science.
Knowledge and understanding
For a passing grade the student must
be able to perform quantum mechanical calculations on systems with spherical symmetry
be able to describe, and in simple cases quantitatively estimate, the energy structure of an atom, using quantum mechanical methods
be able to describe different types of radiation, and the interaction between radiation and matter
have received insight into how different phenomena in atomic and nuclear physics may in principle have the same quantum mechanical background, but with different orders of magnitude, e.g., energy level structures and emission or absorption of radiation
have received a deepened insight into the close and mutual interaction between technology and natural science, and to be aware of and be able to describe typical tecnical applications of atomic and nuclear physics.
Skills and abilities
For a passing grade the student must
have developed his/her ability to plan, perform and analyze experiments and to present scientific results in writing
have improved skills in finding scientific information relevant for a report within the scientific area of the course
have improved skills for written and oral presentations.
