Acquiring the knowledge and competencies in nuclear physics, which represents an important branch of modern physics with implications in a number of basic physical sciences (particle physics, astrophysics, astronomy and cosmology), whose applications on the other hand are the basis of modern technologies: nuclear medicine techniques in the diagnosis and therapy, energy production, dating, examination of the structure of materials, applications in ecology, geology and climatology, nuclear forensics, etc.

Acquiring basic knowledge of nucleosynthesis, the role of thermonuclear reactions and weak interaction processes in the evolution of stars, the nucleon-nucleon interaction, the global properties of atomic nuclei. Gaining knowledge of the most important experiments and practical applications of quantum mechanics and classical electrodynamics in the physics of microscopic finite systems - aggregates of particles that interact through strong, weak, and electromagnetic force.

Providing students the basic knowledge and entry competences for the course Nuclear Physics 2. Together with the course successor, Nuclear physics 2, the goal is to provide students the basic knowledge and entry competencies for specialist courses on fourth and fifth years of study (Medical Physics, Nuclear Astrophysics, Nuclear Structure , Nuclear Physics Laboratory, Structure of Nucleons, Hadron Physics, Reactor Physics) and to connect to the Doctoral Program in Nuclear Physics or some of the above referred fundamental disciplines, as well as with specialist and doctoral studies in medical physics.



1.2 demonstrate profound knowledge of advanced methods of theoretical physics which include classical mechanics, classical electrodynamics, statistical physics and quantum physics
1.3 demonstrate profound knowledge of the most important physics theories, which includes their interpretation, experimental motivation and confirmation, logical and mathematical structure, and description of the related physical phenomena


2.1 develop a way of thinking that allows the student to set the model or to recognize and use the existing models in the search for solutions to specific physical and analog problems
2.3 apply standard methods of mathematical physics, in particular mathematical analysis and linear algebra and corresponding numerical methods when solving physics problems
2.4 apply existing models for understanding and explaining new experimental phenomena and data


4.3 use English as the language of communication in the profession, the use of literature, and writing scientific papers and articles


5.1 consult professional literature independently as well as other relevant sources of information, which implies a good knowledge of English as a language of professional communication


Upon completion of the course the student will be able to:
1. Demonstrate the knowledge and understanding of the basic concepts of stellar evolution, the basic reactions in nucleosynthesis, which includes primordial nucleosynthesis, nucleosynthesis in stars and processes during the evolution of a supernova.
2. Distinguish and explain the properties of different stars in the framework of nuclear physics; the Sun, red giants, white dwarfs, neutron stars, and so on.
3. Explain the structure of nucleons, conservation laws, and isospin.
4. Explain the general form of the nucleon-nucleon interaction starting from symmetries and experimental data on nucleon-nucleon scattering.
5. Explain the role and properties of neutrinos in the context of nuclear processes, as well as the methods for their detection.
6. Connect the most important experimental results on scattering with the properties of nuclear effective interactions and bulk properties of nuclei.
7. Demonstrate knowledge of the properties of the deuteron, to apply quantum mechanics to describe static electric and magnetic moments deuteron.
8. Apply quantum physics and classical electrodynamics in describing the electric and magnetic moments of the atomic nucleus.
9. Demonstrate knowledge of basic bulk properties of atomic nucleus in the context of relevant experiments and phenomenological formalism, in particular the shape, dimensions of the nucleus, and binding energy.
