Abstract
The transverse correlation range and the susceptibility in the critical region has been measured by neutron scattering. A special technique required to resolve the superdiverging longitudinal correlation range has been utilized. The results for together with existing specific-heat data are in remarkable agreement with the renormalization group theory of systems with marginal dimensionality. The ratio between the susceptibility amplitudes above and below was found to be 2 in accordance with renormalization-group and meanfield theory.
