Question

The wavelengths of the Na yellow doublet (²P→ ²S) are equal to 589.59 and 589.00 nm. Find:

(a) the ratio of the intervals between neighbouring sublevels of the Zeeman splitting of the terms ²P_3/2 and ²P_1/2 in a weak magnetic field;

(b) the magnetic field induction B at which the interval between neighbouring sublevels of the Zeeman splitting of the term ²P_3/2 is η= 50 times smaller than the natural splitting of the term ²P.

Answer 1

and the separation between the two sublevels into which the ²P_1/2 term will split is
