Hyperfine structure

  1. Jun 10, 2015 #1
    1. The problem statement, all variables and given/known data
    A transition happens for ##\lambda = 494nm## in the Cesium ions (##^133 Cs##) between a term in the ##5p^5 6s## configuration and term in the ##5p^5 6p## configuration. Five components are observed with the following energies (relative to the transition of least energy): 0, 2.40Ghz, 5.75GHz, 10.07GHz, 15.35GHz.

    Find the value of the nuclear spin of ##^133 Cs## as well as the value of J for the term in the ##5p^5 6s## configuration

    2. Relevant equations


    3. The attempt at a solution

    I am not sure how to solve this. I probably have to use ##F = I + J##, with ##I## being the nuclear spin, which I have to find. I therefore need the value of ##F## and ##J##.

    One of the problems here is that I do not know how to find the S and L for the above configurations.. Any help would be huge!

    What are the ##L,S,J## numbers for the two configurations? What are the selection rules for transitions between them?
