Quantum Mechanical Stationary State Perturbation Theory And Its Teaching And Research

In this paper, the current states of research about the basic theory of stationary state perturbation method are firstly reviewed, on base of them, and studied some physics issues mainly about hydrogen atom. The stark effect of the energy level (n = 4) of hydrogen atom is calculated and the stark effect of three dimensional hydrogen atom is discussed by the use of the parabolic coordinates, then the perturbative matrix elements for each energy level are given. Further more, the removal of the degeneracy of the hydrogen atom is discussed, mainly studying the hydrogen atom in two orthogonal non-uniform electric fields and in high uniform magnetic field. At last, about how to improve teaching stationary state perturbation method is briefly reviewed on base of modern teaching theory and self-study experience.
