Learning and Teaching Methods
The learning outcomes of the module will be achieved via frontal lecture, written and verbal lecturing and powerpoint presentations.
The lecture will be complemented by a weekly exercise class, where students will solve problems under supervision.

Description of exams and course work
There will be an oral exam of 25 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and example calulations.
For example an assignment in the exam might be:
- Give the equation which defines the wavelength of matter. Discuss the dependencies Write down the fission reaction.
- Why do fission neutrons have to be moderated? What means moderation?
- Describe the energy transfer in elastic central collision.
- List typical moderators. Argue about the difference of D2O and H2O as moderator. What are the diffusion length in both moderators?
- Discuss the differences/complementarity of reactor neutron sources and spallation neutron sources.
- Note the different cross sections for thermal neutrons. What is the unit for a cross section?
- What is the relation between sigma_coh and scattering length b?
- Give the definition of the double differential cross section for thermal neutrons.
- Define the scattering vector.
- Note the Laue condition in diffraction. What does it mean?
- Note the Bragg equation. What does it describe?
Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
Remarks on associated module exams
The exam for this module can be taken together with the exam to the associated follow-up module PH2054: Physics with Neutrons 2 / Physik mit Neutronen 2 after the follwoing semester. In this case you need to register for both exams in the following semester.
The exam may be repeated at the end of the semester. There is a possibility to take the exam in the following semester.
