摘要
We report the creation of the first mixture of ^6Li and ^88Sr atoms in an optical dipole trap. Using this mixture,a measurement of the interspecies thermalization process is carried out and the previously unknown interspecies s-wave scattering length between ^6Li and ^88Sr atoms is extracted to be |a6 Li-88 Sr|=(380-100^+160)a0 with a0 being the Bohr radius from the rate of interspecies thermalization.
