Magnetic trapping of an atomic 55Mn-52Cr mixture -: art. no. 025602

Atomic manganese Mn-55 and chromium Cr-52 are simultaneously loaded and confined in a magnetic trap. Using a cryogenic He-3 buffer gas, 10(11) manganese and 10(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(Mn,Cr)=1.5(+/-0.2)x10(-13) cm(3)/s.
