Structural characteristics and available critical exponent measurements fail to distinguish clearly between Ising and Heisenberg critical behavior in Gd. In this context we present a new perturbed ..gamma gamma..-angular correlation measurement of the exponent ..beta.. which appears to resolve the ambiguity. From our result, ..beta.. = 0.399(16), we conclude that Gd is described by Heisenberg critical behavior for reduced temperatures epsilon>10/sup -3/. This does not exclude crossover to another value for smaller epsilon.
