We have investigated chiral edges of a quantum Hall liquid at filling factor (Formula presented) We find that spin and charge separate in the presence of the long-range Coulomb interaction, and the tunneling density of states is given by (Formula presented) The measurement of the temperature and voltage dependences of the tunneling current should reveal the presence of spin-charge separation.
