Magneto-optical trapping of bosonic and fermionic neon isotopes and their mixtures: isotope shift of the ^3P_2 to ^3D_3 transition and hyperfine constants of the ^3D_3 state of Ne-21

摘要: We have magneto-optically trapped all three stable neon isotopes, including the rare Ne-21, and two-isotope combinations. The atoms are prepared in metastable ^3P_2 state manipulated via laser interaction on to ^3D_3} transition at 640.2nm. These cold (T = 1mK) environmentally decoupled atom samples present ideal objects for precision measurements investigation of interactions between ultracold atoms. In this work, we accurate isotope shift ^3D_3 hyperfine constants Ne-21. determined shifts (1625.9\pm0.15)MHz Ne-20 Ne-22, (855.7\pm1.0)MHz (770.3\pm1.0)MHz Ne-21 Ne-22. obtained magnetic dipole electric quadrupole A(^3D_3)= (-142.4\pm0.2)MHz B(^3D_3)=(-107.7\pm1.1)MHz, respectively. All give a reduction uncertainty by about one order magnitude over previous measurements.
