  We present the simultaneous cooling and trapping of an isotopic mixture in a
magneto-optical trap and we describe the transfer of the mixture into a
conservative, far-off resonant dipole trap. The mixture is prepared with a new
technique that applies to intermediate and heavy alkaline earth like atoms. In
this work, 88Sr and 86Sr are simultaneously loaded first into the
magneto-optical trap operated on the 1S0-3P1 spin-forbidden line at 689 nm, and
then transferred into the dipole trap. We observe fast inter-species
thermalization in the dipole trap which allows one to set a lower bound on the
88Sr-86Sr elastic cross section.
