Properties of Atoms. Spectra.

Problem 6.160

It is known that a spectral line \(\lambda=612 \mathrm{nm}\) of an atom is caused by a transition between singlet terms. Calculate the interval \(\Delta \lambda\) between the extreme components of that line in the magnetic field with induction \(B=10.0 \mathrm{kG}\).

Reveal Answer
Δλ=λ2eB/2πmc2=35pm\Delta \lambda=\lambda^{2} e B / 2 \pi m c^{2}=35 \mathrm{pm}
