Electron state change

  1. May 24, 2015 #1
    What are the number of states available to the electrons, and what is the difference between the ease of getting electrons to change states considered against the ease with which they change states by themselves? Can you give an example where they change states by themselves?

    As elements of a Hilbert space its infinite

    Well they can spontaneously changes state - so thats obiously the easiest since it requires nothing.

    Yes - spontaneous emission

    The cause is fluctuations of the vacuum. Note such fluctuations are not real - they are simply mathematical artefacts of the perturbation methods used.

    Thanks
