Certificate of Completion
Scattering is fundamental to almost everything we know about the world, such as why the sky is blue. Tunnelling is entirely quantum-mechanical and gives rise to such phenomena as nuclear fusion in stars. Scattering and tunnelling is a free course that investigates examples and applications of both these fascinating concepts.
Course learning outcomes
After studying this course, you should be able to:
- Explain the meanings of key terms and use them appropriately
- Describe the behaviour of wave packets when they encounter potential energy steps, barriers and wells
- Describe how stationary-state solutions of the Schrödinger equation can be used to analyse scattering and tunnelling
- For a range of simple potential energy functions obtain the solution of the time-independent Schrödinger equation and use continuity boundary conditions to find reflection and transmission coefficients
- Present information about solutions of the time-independent Schrödinger equation in graphical terms.
