Question

Determine the spectral symbol of an atomic singlet term if the total splitting of that term in a weak magnetic field of induction `B= 3.0KG` amounts to `DeltaE= 104 mu eV`.

Answer 1

For single term `S=0, L=J,g=1`
Then the total splitting is `deltaE= 2Jmu_(B)B`
Substitution gives `J=3(=deltaE//2mu_(B)B)`
The term is `.^(1)F_(3)`.
