Influence of a weak electric field on the coherent Rydberg resonances was studied on two-photon transitions 2 S – nD by recording the resonance fluorescence of lithium atoms in a magneto-optical trap. It was observed that an isolated spectral line 2 P – nD transferred to the spectral band width growing with a principal number n (or an electric field E ). It was shown that the frequency tuning of a resonant radiation on the left (right) edge of the band allows to create a gas of Rydberg atoms with fixed and large dipole moments d ∝ ea 0 n 2 ( e is the elementary charge, a 0 is the Bohr radius), oriented against (along) the electric field. The radiation frequency was tuned on the center of the band would produced atomic states with zero dipole moments, but with a big contribution of states with maximum angular momentum quantum number l ~ n .
