NUCLEAR ASTROPHYSICS - 2022/3
Module code: PHY3041
The first part of the module explores different aspects of the structure of atomic nuclei, starting from basic principles and leading to current research themes. There is an emphasis on the physical limits to nuclear binding and nuclear reactions.
The second part of the module explains how nuclei are synthesised in the Universe. Different processes, such as the burning phase, r, s, p are discussed. The relevance of nuclear structure and reaction physics is discussed.

|Assessment type||Unit of assessment||Weighting|
|School-timetabled exam/test||CLASS-TEST (1 hour)||30|
|Examination||EXAM (2 hours)||70|
The assessment strategy is designed to provide the students with the opportunity to demonstrate their knowledge of concepts behind Nuclear Astrophysics.
Thus, the summative assessment for this module consists of:
- A 2 hours duration examination at the end of semester, with a section A of compulsory questions and a section B with 2 questions chosen from 3. (In Part A all questions (40 points); in Part B answer two questions out of three (10-points each). If all three questions in Part B are attempted only the best two will be counted). Full marks in the examination will be equivalent to 70% of the total marks available in assessment of this module.
- A one hour multiple-choice class test on SurreyLearn during week 8. Full marks in the class test will be equivalent of 30% of the total marks available in the assessment on this module.
Formative assessment and feedback:
There will be about 7-8 hour tutorials. The students will receive verbal feedback on their performance during the tutorials.
- provide a basic understanding of the complex structure of atomic nuclei and the limits of their stability. Also how these can be studied via nuclear reactions. To ensure that the student has a clear understanding of the processes in start, and also the information needed from nuclear physics in order to quantify these processes.
|1||Describe the main features of nuclear forces, nuclear shells, collective excitation modes and nuclear stability. They will recognise types of nuclear reactions according to incident energy, impact parameters and outcomes. This knowledge will be applied to nuclear astrophysics. The student will be able to assess the fusion burning in starts, as well as the production of element heavier than iron mainly via neutron induced processes. They will be able to formulate and quantify the reaction rates and the effect of quantum tunnelling and temperature in stars.|
C - Cognitive/analytical
K - Subject knowledge
T - Transferable skills
P - Professional/Practical skills
Methods of Teaching / Learning
33 hours of lectures/tutorials.
Lectures will be used to present the material on the topic of Nuclear Structure.
Starting from week 4, there will be 1 hour long tutorials per week (8 tutorials in total). This will be used for problem solving, based on the material discussed in the lecture sessions. It will test the knowledge of the students and it will provide feedbacks for students on an individual level.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
