Challenge Problems

Push your limits with challenges.

Question 1

If the fine structure splitting in a specific atom is measured as 7 × 10^(-5) eV, and it is caused by spin-orbit coupling, how does this value compare with a typical hyperfine structure splitting? Discuss and calculate a ratio of fine to hyperfine structure if hyperfine is known to be around 1 × 10^(-6) eV.

💡 Hint: Use simple division to find the ratio.

Question 2

Discuss how Zeeman and Stark effects would both impact observed spectral lines in a laboratory and a stellar environment. Provide potential observations from both environments.

💡 Hint: Consider the nature of external fields in both environments.
