**Course Program**

The program entails the teaching of scattering theory with emphasis on chemical reactions. It begins with the treatment of one-dimensional quantum scattering, where students encounter for the first time the S matrix and the time-independent and time-dependent methodologies for the resolution of the Schroedinger equation. Subsequently, the three-dimensional case is treated. The scattering from the classical point of view is treated and afterwards I pass to the quantum point of view where the students encounter concepts such as partial wave analysis and the Born approximation. After an extension to the multichannel case, I pass to reactive scattering. The students make the connection between reactive cross-section and reaction rate constant, the concept of cumulative reaction probability is introduced and approximate models for the calculation of the rate constants are discussed (transition state theory and RRKM model).
