We examine the density profiles of the quantum degenerate Bose-Fermi mixture of {sup 174}Yb-{sup 173}Yb, experimentally observed recently, in the mean-field regime. In this mixture there is a possibility of tuning the Bose-Bose and Bose-Fermi interactions simultaneously using two well-separated optical Feshbach resonances, and it is a good candidate to explore phase separation in Bose-Fermi mixtures. Depending on the Bose-Bose scattering length a{sub BB}, as the Bose-Fermi interaction is tuned the density of the fermions is pinched or swapping with bosons occurs.
