Problem
Laser spectroscopy resolves an electronic level with total electronic angular momentum Je=3/2 into four hyperfine levels. The other level of the observed transition has negligible hyperfine splitting, so the spacings between optical components equal the spacings between these levels. The spacings between adjacent levels, taken in order of increasing F, are measured to be 195MHz, 260MHz and 325MHz. Using the interval rule for magnetic hyperfine structure, determine the nuclear spin J of the atom.
