Measurement of S-Wave Scattering Length between ^6Li and ^88Sr Atoms Using Interspecies Thermalization in an Optical Dipole Trap

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 |a_\rm ^6Li-^88Sr|=(380^+160_-100)a_0 with a_0 being the Bohr radius from the rate of interspecies thermalization.
