“…Interestingly, a perturber attached to the threshold at 637. 40 is attached to this J c = 7 threshold, an s 1/2 Rydberg electron can at most give J = 15/2; combined with the I = 7/2, the largest total angular momentum, F T , could be 11. Thus, we would expect the F T = 12 series to be unperturbed but both of the F T = 11 series to be perturbed.…”

Theory of long-range interactions for Rydberg states attached to hyperfine-split cores

2018

View full text Add to dashboard Cite

The theory is developed for one and two atom interactions when the atom has a Rydberg electron attached to a hyperfine split core state. This situation is relevant for some of the rare earth and alkaline earth atoms that have been proposed for experiments on Rydberg-Rydberg interactions. For the rare earth atoms, the core electrons can have a very substantial total angular momentum, J, and a non-zero nuclear spin, I. In the alkaline earth atoms there is a single, s, core electron whose spin can couple to a non-zero nuclear spin for odd isotopes. The resulting hyperfine splitting of the core state can lead to substantial mixing between the Rydberg series attached to different thresholds. Compared to the unperturbed Rydberg series of the alkali atoms, the series perturbations and near degeneracies from the different parity states could lead to qualitatively different behavior for single atom Rydberg properties (polarizability, Zeeman mixing and splitting, etc) as well as Rydberg-Rydberg interactions (C5 and C6 matrices).

“…Studies of the Rydberg spectra of neutral rare earth elements have been limited to date, with initial measurements of the ionization potentials for the full range of lanthanides [11] and actinides [12] and energy resolved Rydberg states for La [13], Eu [14], Dy [15], Lu [16], Gd [17], Sm [18], Th [19], Ce [20], Yb [21], Ac [22], Pu [23] and U [24]. In this paper we present the first high resolution spectroscopy of the 4f 11 6sns and 4f 11 6snd odd-parity Rydberg states of Ho in the range n = 40 − 101 using depletion measurements * hostetter@wisc.edu † msaffman@wisc.edu on a magneto optical trap (MOT).…”

Measurement of holmium Rydberg series through magneto-optical trap depletion spectroscopy

et al. 2015

We report measurements of the absolute excitation frequencies of 165 Ho 4f 11 6sns and 4f 11 6snd odd-parity Rydberg series. The states are detected through depletion of a magneto-optical trap via a two-photon excitation scheme. Measurements of 162 Rydberg levels in the range n = 40 − 101 yield quantum defects well described by the Rydberg-Ritz formula. We observe a strong perturbation in the ns series around n = 51 due to an unidentified interloper at 48515.47(4) cm −1 . From the series convergence, we determine the first ionization potential EIP = 48565.939(4) cm −1 , which is three orders of magnitude more accurate than previous work. This work represents the first time such spectroscopy has been done in Holmium and is an important step towards using Ho atoms for collective encoding of a quantum register.

“…The Rydberg states of Yb + have been the subject of recent, but very limited, investigations. More specifically, the abnormal branching ratios in laser-excited series of this ion have been investigated by Zhao et al (1996) and by Xu et al (1997). Laser lifetime measurements, however, for highly excited levels along the series, are missing so far.…”

New radiative lifetimes, measured by time-resolved laser-induced fluorescence spectroscopy, are reported for five Rydberg states of singly ionized ytterbium. Free Yb + ions were produced in a laser-induced plasma. The experimental results have been compared with HFR calculations, taking core-polarization effects into account, and a good agreement (within 25%) between theory and experiment is observed for four levels. HFR results are also proposed for np (n 7) and nf(n 8) Rydberg states and compared with available data.
