Phys. Rev. Lett. 96, 030401 (2006) [4 pages]Molecules of Fermionic Atoms in an Optical LatticeReceived 8 September 2005; published 23 January 2006 We create molecules from fermionic atoms in a three-dimensional optical lattice using a Feshbach resonance. In the limit of low tunneling, the individual wells can be regarded as independent three-dimensional harmonic oscillators. The measured binding energies for varying scattering length agree excellently with the theoretical prediction for two interacting atoms in a harmonic oscillator. We demonstrate that the formation of molecules can be used to measure the occupancy of the lattice and perform thermometry. © 2006 The American Physical Society URL:
