Field Interaction with “Free Charges”

While studying Chap. 1 you probably paid attention to the fact that as far as complication of a microparticle’s internal structure is concerned, its energy spectrum becomes more and more dense. In a hydrogen atom the energy of stationary states depends only upon the main quantum number. For a lithium atom, stationary states with different orbital number values become distinguishable. If several electrons are located in the external orbit, the energy value begins to depend upon the complete mechanical moment of these electrons. When transferring to molecules, we must add vibrational and rotational forms of motion. As a result, vibrational–rotational energy sublevels appear for each electron level. The dimensions of operator matrices quickly increase and the problem of interaction of a particle and emission becomes very bulky.
