By means of the 1/n expansion method, the critical exponent η is discussed for the three-dimensional isotropic n-vector model with short-range interaction. Terms up to 1/n2 are obtained and the result is compared with the numerical estimate based on high temperature expansion and with Wilson's ε expansion.
