Abstract

The authors have demonstrated the production of molecular Rydberg state in K 2 by means of two-step photoexcitation with help of thermionic detection in a disc-shaped heat-pipe oven. Preliminary results concern a spectroscopic investigation of the very high 'Rydberg region'. Results of the pressure shift of Rydberg lines are also presented.

Self-shift and foreign-gas-induced shift of molecular Rydberg states measured in a thermionic heat-pipe oven

Anthony F. J. van Raan, Jos E. M. Haverkort, J Korving

By a simple technique it is possible to discriminate experimentally between the self-shift and foreign-gas-induced shift of Rydberg levels excited in a heat-pipe system. Illustrative results for two particular rydberg levels of the potassium dimer K 2 are presented. The results concern the shift induced by the alkali itself and the shift induced by Ar and He. Earlier reported discrepancies are removed.

Collision-induced shifts of Rydberg levels of strontium

M. Marafi, K. S. Bhatia, Yacoub Makdisi +1 more

Measurements of spectral line shifts induced by collisions with rare gas perturbers are reported. High Rydberg states were prepared by multiphoton excitation using an excimer pumped tunable dye laser. A thermionic detector inside a heat pipe was used to collect the ionization products resulting from excited states. Analysis of the data for the shifts of the absorption transition to 5snd 1D 2 states in strontium is presented.

Thermoelectronic diode used to detect Rydberg states in atoms——experimental observation and theoretical analysis

Li P

We have detected the two-photon absorption signals of Ba in a heat-pipe cell using a thermoelectronic diode. The relations between signal characteristics and pressure, temperature, bias voltage, position of interaction zone were studied both experimentally and theoretically.

Collisions between Sr Rydberg atoms of intermediate and high principal quantum numbers and noble gases at thermal energies

K -D Heber, P. J. West, Eckart Matthias

Pressure shift and broadening measurements of 5snd 1 D 2 and 5snd 3 D 2 Rydberg states of Sr I due to Xe have been performed in the range 8<or=n<or=35 by means of Doppler-free two-photon excitation, combined with thermionic detection and the use of a molecular frequency standard. The data show striking differences between pressure shifts and broadenings of singlet and triplet states, which up to now have not been predicted by theory.

Spectroscopy of the KRb molecule

Jin‐Tae Kim, Bongsoo Kim, William C. Stwalley

Mathjax On | Off Abstract In this section we summarize experimental spectroscopic investigations of KRb. Since structureless bands with a peak at 495.9 nm, in the case of the KRb molecule, were first observed in the vapor state of the alkali metals, there have been many spectroscopic studies using KRb molecules formed in a heat-pipe oven, in a MB machine, in PA of ultracold atoms, in UMs, and in our combination method between MB and UM.

Production of high-nstrontium Rydberg atoms

The photoexcitation of strontium Rydberg atoms with n ~ 300 is being examined using a crossed laser-atom beam approach to enable study of quasi-stable two-electron excited states and of strongly-coupled Rydberg systems.
