【 摘 要 】

We study magneto-optical trap (MOT) of Mg atoms operating on the closed triplet3P2→3D3(λ = 383.3 nm) transition formed by the light waves with elliptical polarization ( configuration). Compare to well-known trap formed by light waves with circular polarization (σ+-σ-configuration) the suggested configuration offer the lower sub-Doppler temperature for trapped Mg atoms, that can't be reached in conventional σ+-σ-MOT.
