Abstract

Abstract: We report on the measurement of the scattering properties of ultracold 174 Yb 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 174 Yb atoms in different collisional channels involving the ground state 1 S0 and the metastable 3 P0 states are derived. These studies set important constraints for future experimental studies of two-electron atoms for quantum-technological applications.
