We characterize the ground state and excitation spectrum of the S=1/2, nominally pure and perfect kagomé system ZnCu3(OH)6Cl2 using the following measurements: magnetization, muon spin rotation frequency shift K, transverse relaxation time T2∗, and zero field relaxation, and Cl nuclear spin-lattice relaxation T1. We found no sign of singlet formation, no long range order or spin freezing, and no sign of spin-Peierls transition even at temperatures as low as 60 mK. The density of states has E1/4 energy dependence with a negligible gap to excitation.
