Hyperfine and fine structure ENERGIES

  1. Feb 5, 2004 #1
    What are the approximate relative sizes of the following energies?

    a) The n = 1 to n = 2 energy difference in hydrogen and the rest mass mc^2 of an electron

    b) The n = 1 to n = 2 energy difference in hydrogen and a typical fine structure splitting in hydrogen

    c) A typical fine structure splitting in hydrogen and a typical hyperfine structure splitting in hydrogen

    a) I know that E = -Ryd/n^2 where Ryd is Rydberg = -(m*e^4)/(2hbar^2)...do I just plug in constants and explain the difference between the two energies

    b) and c ) I know that uI is approximately 1000 times smaller than uE but what does that have to do with energies?

    Depsarately need help !

    anything?

    a) yes... and you should be able to work out the rest mass of an electron fairly easily.
