Course description
Based on the mathematical basis completed in the course "Quantum Mechanics I", the quantum-mechanical description of one electron in central field, i.e., the theory of hydrogenic atoms is given as a typical example of the 3 dimensional quantum systems.
Expected Learning
1) To become able to build a Schrodinger equations for a particle in the the 3 dimensional space.
2) To become able to separate multi-variables differential equation into a set of one dimensional equations.
3) To become able to derive the spherical harmonics and to identify them as the wave funtions corresponding to angular momenta.
4) To become able to derive the radial wave functions for electrons in the central coulomic field corresponding to the eigen values of total mechanical energies.

  (5-5) The solutions of the associated Laguerre differential equation.
  (5-6) Comparison of the solutions with the Bohr model.
Prerequisites
Although it is not necessary to complete the credits of the courses "Introduction to Quantum Mechanics" and "Quantum Mechanics I", the idea and method given in those courses are used as common.
So it is necessary to understand the contents of the courses "Introduction to Quantum Mechanics" and "Quantum Mechanics I".
Required Text(s) and Materials
Not specified.
Every typical textbook of quantum mechanics describes the theory for hydorgenic atoms.
References
Theoretical bases are mainly taken from B.H.Bransden&J.Joachain, "Physics of Atoms and Molecules, 2nd Ed." (2009,Prentice Hall) and W. Greiner, "Quantum Mechnics, An Introduction, 4th Ed." (2001,Springer).
However, detailed derivations are taken elsewhere.
Assessment/Grading
Evaluated by homeworks and a semester examination.
Message from instructor(s)
Quantum mechanics is one of the methods to solve physical phenomena into elementary problems. It looks complicated at a first glance. However, if you confirm the each steps of derivation, you will be surprised that the theory is constructed with plain methmatical methods, so that it is highly understandable.
We remark that the way of quantum-mechanical understanding on the natural phenomena will be your most important capability for a physical engineer.
