摘要：

We study the implementation of Monte Carlo renormalization group (MCRG) in momentum space. This technique is most efficient when used in combination with a Fourier accelerated Langevin algorithm. As a benchmark we calculate the critical exponents nu and eta in the vicinity of both the gaussian and the Wilson fixed point in lambda phi(3)(4). The results are very competitive with alternative analytical methods and require a moderate computational effort only.
