 note = {Low energy properties of theS 1=2antiferromagnetic Heisenberg chains with Fibonacci exchangemodulation are studied using the real space renormalization group method for strong exchange modulation. Using the analytical solution of the recursion equation, the true asymptotic behavoir isrevealed, which was veiled by the  nite size effect in the previous numerical works. It is found that theground state of this model belongs to a new universality class with a logarithmically divergent dynamical exponent which is neither like FibonacciXYchains nor likeXYchains with relevantaperiodicity., Copyright notice. c2004 American Physical Society.
