Content, Learning Outcome and Preconditions

Content

  1. Elastic X-ray scattering at an electron, atom, molecule and protein crystal

  2. The Phase problem of X-ray structure analysis and how to solve it

  3. Static structure distribution and dynamics of biomolecules

  4. Diffuse scattering

  5. Time resolved X-ray structure determination with the Laue method

  6. Elastic and inelastic neutron scattering

  7. Small angle scattering

  8. Generation and detection of X-rays and neutrons

Learning Outcome

After successful participation in this module, the students master crystal structure analysis with X-rays and neutrons as complementary methods. For them, reciprocal space is a tool for simple and fast visualization of scattering processes. The students understand the importance of the energy resolution of a scattering method, the difference between static structure distribution and dynamic of the molecule.

Preconditions

There are no prerequisites required exceeding the admission requirements for the Master's programme.

Courses, Learning and Teaching Methods and Literature

Courses and Schedule

Learning and Teaching Methods

Within the lecture it is explained, how the three-dimensional structure of biomolecules like proteins or DNA can be obtained by the coherent scattering of X-rays and neutrons. The generation of X-rays and neutrons, their specific interaction with the sample and their detection will be discussed. An active participation of the students in the form of questions, comments and discussions is very welcome. The acquired knowledge is deepened by exercises in which the learned is applied in the form of illustrative calculations.

Media

The contents of the course will be presented as PowerPoint slides. Supplements are either written directly into the slides or onto the whiteboard. A pdf version of the content without the supplements is available on Moodle shortly before the start of each lecture.

Module Exam

Description of exams and course work

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 60 minutes.

Exam Repetition

The exam may be repeated at the end of the semester.
