Abstract: We report on the measurement of the scattering properties of ultracold 174Yb bosons in a three-dimensional optical lattice. Site occupancy in an atomic Mott insulator is resolved with high-precision spectroscopy on an ultranarrow, metrological optical clock transition. Scattering lengths and loss rate coefficients for 174Yb atoms in different collisional channels involving the ground state 1S0 and the metastable 3P0 states are derived. These studies set important constraints for future experimental studies of two-electron atoms for quantum-technological applications.
