Publisher's Synopsis
The theory of low energy collisions is discussed, especially those occurring with velocities similar to those in room temperature gases. A balance has been aimed for, between the classical and quantum approaches and the between the four main branches of the subject: elastic, inelastic and reactive scattering and electron excitation. An understanding of the theory should be expected now of anyone intending to do research in gas-phase spectroscopy, or reactivity, or in many other branches of physics and chemistry.
