Scattering and Decay processes are the main phenomena that
provide us information about the (sub)atomic world.
In this course the various techniques are outlined which are
used to acquire knowledge about the nature of the elementary
building blocks of matter and the interactions among them.
By means of a classical description of Rutherford scattering,
the concept of Cross Section is introduced.
This is then applied to experiments with particle accelerators
to introduce the concept of Luminosity and derive expressions
for Event Rate, Mean Free Path and Beam Attenuation.
The physics aspects are addressed by investigation of subjects
like Transition Rates, Average Lifetimes, Radiation Intensity
and the Lineshape of unstable states.
