This expression is the same as that obtained by Bohr. Thus the introduction of elliptical orbits gives no new energy levels and hence no new transition. Atomic physics, Introduction to Atomic Physics,, We will study relativistic quantum mechanics in detail in Chapter 11 but, for now, consider the case of the hydrogen atom, which is an ideal system for starting to understand the connection. One of the reasons for this is that the speed of an electron in the ground state of the hydrogen atom is ….
