Parallel static dipole polarizability of the ground state and of the lowest triplet state of (crosses and plus symbols) and LiCs (closed circles and open circles) as computed with our quantum chemistry approach using basis set A (solid lines) or basis set B (dashed lines) of Ref. 28 (of Ref. 30 for Cs).

Table I.

Static dipolar polarizabilities (in a.u.) of alkali atoms compared to the available experimental and recent theoretical works. Both nonrelativistic (a) and relativistic (b) values calculated by Kellö et al. (Ref. 54) are displayed.

Table II.

Present polarizability values (in a.u.) for the ground state of homonuclear alkali dimers, taken at the experimental equilibrium distance (except for ), and compared to the available theoretical works. For the latter, the distance at which the polarizabilities are calculated is also displayed, when available.

Table IV.

Present polarizability values (in a.u.) for the ground state of heteronuclear alkali dimers, taken at the experimental (when available) or the theoretical (from Ref. 28) equilibrium distances, and compared to other published theoretical results.

Average polarizabilities and anisotropies computed in the present work for the singlet ground state and lowest triplet states of all alkali pairs. Values are listed for the lowest vibrational level , and for the level where the maximum value is reached for the ground state.

Present average polarizability (in a.u.) for the ground state of homonuclear alkali dimers, computed for their level. The values for are compared to the experimental measurements in Refs. 43, 47, and 44 [row (a)] at various temperatures of their thermal beam, and extrapolated to following Refs. 55 and 44 [row (b)], i.e., for the level.

Present average polarizability (in a.u.) ground state of heteronuclear alkali dimers, computed for their level. As for the homonuclears we report the experimental values for NaK and KCs, as well as the estimates for all the heteronuclear species from Ref. 44 (see text and Table VI, and the experimental value of Ref. 45 for NaLi.

Summary of the properties (anisotropy , rotational constant , permanent dipole moment ) of mixed alkali pairs relevant for their orientation and alignment induced by external fields, for the lowest vibrational level of their ground state. The values for the laser intensity of a cw laser field, and for an external static electric field correspond to and , respectively (see text). We also report such properties for the vibrational level with maximal computed anisotropy.
