Electron collisions with atoms ions and molecules have been investigated since the earliest
years of the last century because of their pervasiveness and importance in fields ranging from
astrophysics and plasma physics to atmospheric and condensed matter physics. Written in an
accessible yet rigorous style this book introduces the theory of electron-atom scattering into
both the non-relativistic and relativistic quantum frameworks. The book also includes exercises
with an increasing degree of difficulty to allow the reader to become familiar with the
subject.
