Abstract
Atomic manganese {sup 55}Mn and chromium {sup 52}Cr are simultaneously loaded and confined in a magnetic trap. Using a cryogenic {sup 3}He buffer gas, 10{sup 11} manganese and 10{sup 12} chromium atoms are trapped at an initial temperature of 600 mK. The buffer gas is then pumped away, thermally isolating the sample. The Mn-Cr interspecies inelastic rate constant is measured to be {gamma}{sub Mn,Cr}=1.5({+-}0.2)x10{sup -13} cm{sup 3}/s.
Highlights
The ability to simultaneously cool and trap multiple species has paved the way for the exploration of a variety of physical phenomena not previously accessible with a single species
Requires that the atom has a strong cycling transition at an accessible wavelength; it has far been limited to binary mixtures of either alkali metals or metastable noble gases8͔
Mn and Cr atoms are produced via laser ablation of solid metal targets inside a cylindrical plastic/copper composite cell maintained at 600 mK by a 3He refrigerator through a copper thermal link
Summary
Magnetic Trapping of an Atomic 55Mn-52Cr Mixture. Atomic manganese 55Mn and chromium 52Cr are simultaneously loaded and confined in a magnetic trap. Using a cryogenic 3He buffer gas, 1011 manganese and 1012 chromium atoms are trapped at an initial temperature of 600 mK.
