The magnetic excitations of the quasi-2D spin-1/2 Heisenberg antiferromagneton an anisotropic triangular lattice Cs2CuCl4 are explored throughout the 2DBrillouin zone using inelastic neutron scattering. In the spin liquid phaseabove the transition to magnetic order extended excitation continua areobserved, characteristic of fractionalization of S=1 spin waves into pairs ofdeconfined S=1/2 spinons and the hallmark of a resonating-valence-bond (RVB)state. The weak inter-layer couplings stabilize incommensurate spiral order atlow temperatures and in this phase sharp magnons carrying a small part of thetotal scattering weight are observed at low energies below the continuum lowerboundary. Linear spin-wave theory including one- and two-magnon processes candescribe the sharp magnon excitation, but not the dominant continuumscattering, which instead is well described by a parameterized two-spinoncross-section. Those results suggest a cross-over in the nature of excitationsfrom S=1 spin waves at low energies to S=1/2 spinons at medium to highenergies, which could be understood if Cs2CuCl4 was in the close proximity of atransition between a fractional spin liquid and a magnetically-ordered phase.Comment: 18 pages revtex, 12 ps figure
