Phys. Rev. Lett. 103, 200401 (2009) [4 pages]Bose-Einstein Condensation of Strontium
See accompanying Physics Viewpoint We report on the attainment of Bose-Einstein condensation with ultracold strontium atoms. We use the 84Sr isotope, which has a low natural abundance but offers excellent scattering properties for evaporative cooling. Accumulation in a metastable state using a magnetic-trap, narrowline cooling, and straightforward evaporative cooling in an optical trap lead to pure condensates containing 1.5×105 atoms. This puts 84Sr in a prime position for future experiments on quantum-degenerate gases involving atomic two-electron systems. © 2009 The American Physical Society URL:
