試題 :
1.Please explain the four quantum number in an atom.
2.In a hydrogen atom without any external perturbation,which (one or more)
quantum number(s) determine(s) the energy level?
3.In a quantum well of three quantized state (state 1,2 and 3), what photon-
involved transition(s) (photon absorption or emission) can occur?
4.In a semiconductor quantum-well structure , can we expect photon involved
transition from the first quantize level in the conduction band? why?

and nickle.

vibration energy level transition,and electron state transition in a
molecule.
