Absolute frequency of cesium 6S<sub>1/2</sub>–6D<sub>3/2</sub> hyperfine transition with a precision to nuclear magnetic octupole interaction

Doppler free spectroscopy was performed on the 7p1/2 and 7p3/2 states in neutral cesium-133 using a frequency doubled titanium sapphire laser stabilized to a temperature-stabilized ultra-low expansion optical cavity. The absolute frequencies for the centers of gravity of the two states were determined to be cm−1 and cm−1, factors of 500 and 650 better than previously reported measurements, respectively. The magnetic dipole and electric quadrupole constants were measured to be MHz for the 7p1/2 state and MHz and MHz for the 7p3/2 state, which are consistent with previously published values.

“…6(b). Two-photon excitation at 885 nm, utilized in previous experiments [63,64], can be used to prepare Cs atoms in the 6D 3/2 state. Then, a laser at 1144 nm can be used to photo-associate nP J RAIMs of Cs.…”

We propose a novel type of Rydberg dimer, consisting of a Rydberg-state atom bound to a distant positive ion. The molecule is formed through long-range electric-multipole interaction between the Rydberg atom and the point-like ion. We present potential energy curves (PECs) that are asymptotically connected with Rydberg nP -or nD-states of rubidium or cesium. The PECs exhibit deep, long-range wells which support many vibrational states of Rydberg-atom-ion molecules (RAIMs). We consider photo-association of RAIMs in both the weak and the strong optical-coupling regimes between launch and Rydberg states of the neutral atom. Experimental considerations for the realization of RAIMs are discussed.

“…However, the theoretical predictions of hyper ne structures of D state remains a challenge because of complex electron cloud distribution and strong correlation effects. Therefore, accurate measurement of D states is particularly important for testing computational treatment of correlation, and clarifying the inconsistency between theoretical and experimental results [9,10]. The hyper ne splitting frequency intervals of D state are often anomalously small and even inverted, so it is critical to obtain the spectra between excited states with narrow linewidth and high signal-to-noise ratio for precise measurement [1].…”

Based on cesium 6S1/2 − 6P3/2 − 6D5/2 (852 nm + 917 nm) ladder-type system, we simultaneously obtain the Doppler-free saturated absorption spectroscopy (SAS) of the 6S1/2 − 6P3/2 transition and optical-optical double resonance (OODR) spectroscopy of the 6P3/2 − 6D5/2 transition when the frequency of 852 nm laser is scanned over the 6S1/2 − 6P3/2 transition while keeping the 917 nm laser resonant on the 6P3/2 − 6D5/2 transition. The SAS as a frequency scale is used to measure the frequency intervals of hyperfine splitting of the 6D5/2 excited state via the OODR spectra. With the measured values of hyperfine splitting, the hyperfine coupling constants of the 6D5/2 state are determined as magnetic dipole Ahfs = -4.60 (5) MHz and electric quadrupole Bhfs = 0.23 (47) MHz, which are consistent with previous results. A simple and self-calibration method of measuring the unknown hyperfine structure of an atomic excited state using its own known hyperfine splitting of another state is demonstrated without the aid of any extra frequency calibration tools.
