Abstract

We report a study of a model of a magneto-optical trap (MOT) for atoms 6Li in the field with configuration produced by the counterpropagating elliptically polarised waves, which are in resonance with the optical transition 2S1/2 → 2P3/2 (λ = 670.977 nm). The model takes into account hyperfine splitting of levels inside the natural linewidth of the optical transition. In contrast to a conventional MOT formed by counterpropagating circularly polarised waves (σ + - σ - configuration), the suggested MOT may provide a deeper sub-Doppler cooling of 6Li atoms.
