The nature of the ground state of the spin-1/2 kagome lattice antiferromagnet remains an important question. Cu(1,3-bdc) is a hybrid organometallic compound featuring S=1/2 Cu2+ ions arranged on a kagome lattice. Our previous measurements suggest that at temperatures below 1.8 K this system enters a quasi-static phase with no long range order but extremely slow spin fluctuations. We propose to measure spin excitations of single crystals of Cu(1,3bdc) in this quasi-static phase down to low energies at a variety of applied fields. Our proposed experiments serve two purposes. First, we plan to measure conventional magnon excitations in the high-field saturated phase to determine parameters of the spin Hamiltonian in this system. We will also investigate a previously observed dispersive excitation throughout the Brillouin zone, and measure its dependence on applied field.
