HEAVY IONS PHYSICS

The course aims at giving the basic concepts and important tools to interpret and to study the phenomelogy of heavy ions nuclear reactions. The understanding and critical analysis of scientific papers are essential elements of the learning objectives of the course.

Knowledge and Understanding

Remarkable acquaintance with the scientific method, understanding of nature and of the research procedures in Physics. During the course the student will familiarize with main fundamentals of the phenomenology of nuclear reaction of heavy ions.

Applying Knowledge and Understanding

Ability to identify the essential elements in a nuclear reaction of heavy ions, in terms of orders of magnitude and approximation level, and being able to perform the required approximations. Ability to plan and apply experimental and theoretical procedures to solve problems in academic or applied research, or to improve existing results. Ability to develop new and innovative approaches and methods.

Making Judgements

Ability to convey own interpretations of physical phenomena, when discussing within a research team. Developing one's own sense of responsibility, through the choice of optional courses and of the final project.

Communication Skills

Ability to discuss about advanced physical concepts, both in Italian and in English.
Ability to present one's own research activity or a review topic both to an expert and to an non-expert audience. These abilities will be developed in the framework of a description of phenomena related to nuclear reactions and their interpretations.

Learning Skills

Ability to acquire adequate tools for the continuous update of one's knowledge and to access to specialized literature both in the specific field of nuclear reactions at Fermi energies and in closely related fields.

The course is based on lectures and lesson. Critical reading and understanding of scientific papers related to course topics.

The assessment consists in an oral exam. By means of questions related to key topics of the course content, the global level of knowledge reached by the student will be tested as well as the ability to perform a scientific reasoning of the course topics and to connect different arguments. The students will start with a presentation of one of the scientific paper discussed, followed by questions.

Should the circumstances require online or blended teaching, appropriate modifications to what is hereby stated may be introduced, in order to achieve the main objectives of the course.

Exams may take place online, depending on circumstances.
