Détermination théorique et expérimentale des forces d'oscillateur des transitions de l'atome de césium

Abstract

A theoretical determination of oscillator strengths for the cesium atom is proposed. The values obtained are compared with experimental results deduced from the emission spectra of a slightly ionized quiescent cesium plasma discharge.

Dynamical polarizability of atoms in arbitrary light fields: general theory and application to cesium

“…Before we proceed, we note that, in order to search for red-and bluedetuned magic wavelengths for a far-off-resonance trap, the scalar and tensor polarizabilities of the ground and excited states of atomic cesium have been calculated [19][20][21]. Relevant parameters were taken from a number of sources [15,[49][50][51]. Very recently, the vector light shifts of cesium atoms in a nanofiber-based trap have been studied [30].…”

Photoionization from the 6p2P3/2state of neutral cesium

“…Figure 4 illustrates the present and the previously reported f values of the 6p 2 P 3/2 → nd 2 D 5/2 transitions. The closed squares represent the present work which is extended to n = 60, whereas the closed circles (5 n 11) are the theoretical 5 results and triangles (15 n 19) represent the experimental f values reported by Fabry and Cossent [28]. The insert in Fig.…”

“…A few groups have reported the oscillator strengths of the lower transitions [23][24][25][26][27][28]. Fabry and Cussenot [28] reported both theoretical and experimental oscillator strengths of the lower transitions originating from the 6p 2 P 3/2 excited state. Figure 4 illustrates the present and the previously reported f values of the 6p 2 P 3/2 → nd 2 D 5/2 transitions.…”

“…As the studies of the Rydberg states are mainly focused on the two-photon transitions from the ground state, the oscillator strength of the cesium transitions are limited to the principal series and to the low-lying transitions [23][24][25][26][27][28]. Fabry [27] reported the f values of the principal series and of various excited transitions taking into account the effect of atomic core polarization.…”

“…Fabry [27] reported the f values of the principal series and of various excited transitions taking into account the effect of atomic core polarization. Thereafter, Fabry and Cussenot [28] determined the oscillator strength, theoretically as well as experimentally, of the principal series and of the transitions among the ns, np, nd, and nf series. Lahiri and Manson [29] calculated the oscillator strength among the ground state and the s, p, d, and f excited states (up to n = 9) and compared their results with the experimental and the semiempirical results.…”
