摘要: We report Bose-Einstein condensation of two isotopes the highly magnetic element dysprosium: 162Dy and 160Dy. For 162Dy, condensates with 10^5 atoms form below T = 50 nK. find evaporation efficiency for isotope 160Dy to be poor; however, by utilizing a low-field Fano-Feshbach resonance carefully change scattering properties, it is possible produce condensate 10^3 atoms. The BEC reported an order magnitude larger in atom number than that previously 164Dy BEC, may produced within 18 s.
