The pure electric field level-crossing of mF Zeeman sublevels of hyperfine F levels at two-step laser excitation was described theoretically and studied experimentally for the nD 3/2 states in Cs with n = 7, 9 and 10, by applying a diode laser in the first 6S 1/2 → 6P 3/2 step and a diode or dye laser for the second 6P 3/2 → nD 3/2 step. Level-crossing resonance signals were observed in the nD 3/2 → 6P 1/2 fluorescence. A theoretical model was developed to describe quantitatively the resonance signals by correlation analysis of the optical Bloch equations in the case when an atom simultaneously interacts with two laser fields in the presence of an external dc electric field. The simulations described well the experimental signals. The tensor polarizabilities α2 (in a 3 0 ) were determined to be 7.45(20) × 10 4 for the 7D 3/2 state and 1.183(35) × 10 6 for the 9D 3/2 state; a well established α2 value for 10D 3/2 was used to calibrate the electric field. The α2 value for the 7D 3/2 state differed by ca. 15% from the existing experimentally measured value.

“…To predict the resonance positions, we computed the energy level splitting diagram in the presence of an electric field for hfs levels in the nD 3/2 states of Cs under study (see Fig. 1) using α 2 values calculated by Wijngaarden and Li [13]. We performed this calculation, whose results are shown in Fig.…”

“…Table V compares the present experimental, present theoretical, and past theoretical polarizability results. Our measurements agree well with Coulomb approximation (CA) calculations [10]; however, the CA calculations are not expected to be of high precision. The agreement is also good with the more sophisticated relativistic all-order calculations of Refs.…”

We report polarizability measurements of atomic cesium's 6d 3/2 state. The scalar and tensor polarizabilities are determined from hyperfine-resolved Stark-shift measurements using two-photon laser-induced-fluorescence spectroscopy of an effusive beam. The resulting values are α 0 = −5310(180)a 3 0 and α 2 = 8650(260)a 3 0 . In addition, our measurements yield the hyperfine coupling constants A = 16.36(15) MHz and B = −0.7(8) MHz, which agree with previous measurements. We also present relativistic all-order calculations of both scalar and tensor polarizabilities. The resulting theoretical values, α 0 = −5686(121)a 3 0 and α 2 = 8750(82)a 3 0 , are in agreement with the present experimental results.

Spectroscopic measurements of low‐n Balmer line profiles of atomic hydrogen and deuterium, emitted within the edge region of the TEXTOR‐94 tokamak plasma, have revealed the existence of a class of cold excited atoms, whose probable origin has been ascribed to electron impact‐induced molecular dissociation. Associated with these cold radiators are a second group of ‘lukewarm’ atoms, i.e. atoms heated by elastic collisions with hot protons (deuterons) diffusing outward from the plasma interior, as well as a third group of ‘hot’ atoms, produced in the corresponding excited states directly by charge‐exchange recombination between protons (deuterons) and boundary region atoms. A mechanism recently proposed to explain the heating process quantitatively, in terms of elastic atom‐ion collisions, is applied and discussed in this paper.
