Hyperfine structure transition of Cs-133: calculation?

Click For Summary
SUMMARY

The discussion centers on the theoretical calculation of the hyperfine structure transition frequency of Cs-133, which is crucial for atomic clocks that define the second according to SI Units. The specific frequency of 9,192,631,770 Hz is highlighted as the standard for measuring time. Participants clarify the correct nomenclature, confirming the element in question is Cesium (Cs), not Calcium (Ca). The conversation emphasizes the need for detailed theoretical insights into the hyperfine Hamiltonian specific to Cs-133.

PREREQUISITES
  • Understanding of hyperfine structure in atomic physics
  • Familiarity with quantum mechanics principles
  • Knowledge of atomic clock technology
  • Basic concepts of frequency measurement in SI Units

I'm looking for the theoretical calculation of the hyperfine structure transition frequency of Ca-133 which is used in atomic clocks to define the second according to SI-Units. Google, Google... there is a lot about the hyperfine Hamiltonian of hydrogen, but couldn't find none about that of Ca-133. I would like to see how that famous 9,192,631,770 Hz frequency which defines our earthly time standard is calculated through theory. Can anyone help?

I think it should be Caesium not Calsium.

Opss... You are right, Cs-133... not Ca. Thanks.
