摘要：

Using inelastic scattering of polarized neutrons at a reduced wavevector \q\ = 0.81 q, transverse to the (200)-Bragg reflection (q(d) is thc dipolar wavenumber) the dynamics of longitudinal spin fluctuations have been measured. The data analysis using a maximum entropy algorithm near T(c) is consistent with a double peak lineshape resembling a recent prediction of numerical mode-mode coupling work.
