Phys. Rev. Lett. 103, 090801 (2009) [4 pages]Collisional Losses, Decoherence, and Frequency Shifts in Optical Lattice Clocks with BosonsReceived 14 April 2009; published 28 August 2009 We have quantified collisional losses, decoherence and the collision shift in a one-dimensional optical lattice clock on the highly forbidden transition 1S0-3P0 at 698 nm with bosonic 88Sr. We were able to distinguish two loss channels: inelastic collisions between atoms in the upper and lower clock state and atoms in the upper clock state only. Based on the measured coefficients, we determine the operation parameters at which a 1D-lattice clock with 88Sr shows no degradation due to collisions on the fractional uncertainty level of 10-16. © 2009 The American Physical Society URL:
