Problem 6.162

A spectral line caused by the transition \({ }^{3} D_{1} \rightarrow{ }^{3} P_{0}\) experiences the Zeeman splitting in a weak magnetic field. When observed at right angles to the magnetic field direction, the interval between the neighbouring components of the split line is \(\Delta \omega=1.32 \cdot 10^{10} \mathrm{~s}^{-1}\) Find the magnetic field induction \(B\) at the point where the source is located.
