Measurement of the hyperfine coupling constants and absolute energies of the 12s S-2(1/2), 13s S-2(1/2), and 11d(2)D(J) levels in atomic cesium

We report measurements of the absolute energies of the hyperfine components of the 12s S-2(1/2) and 13s(2)S(1/2) levels of atomic cesium, Cs-133. Using the frequency difference between these components, we determine the hyperfine coupling constants for these states, and report these values with a relative uncertainty of similar to 0.06%. We also examine the hyperfine structure of the 11d D-2(J) (J = 3/2, 5/2) states, and resolve the sign ambiguity of the hyperfine coupling constants from previous measurements of these states. We also derive new, high precision values for the state energies of the 12s S-2(1/2), 13s(2)S(1/2), and 11d D-2(J) states of cesium.
