We present inelastic neutron scattering data on critical dynamics of hFe 18% and 16% disordered ferromagnets. The concentrations of samples were close to the critical value (xc N 15.5%) where ferromagnetism disappears and spin-glass sets in. The value of the dynamic critical exponent z for &aFe 18%

The electromagnetic field of an incoming wave has already been found to be enhanced close to the surface of a thin granular or rough silver film. We use Surface Enhanced Resonant Raman Scattering (SERRS) as a test of this enhancement close to the percolation threshold (Pc)-The scattered light shows

We report on photon scattering (Ξ³ , Ξ³ ) experiments to measure the detailed dipole strength distribution between about 3 and 10 MeV in the Z = 20 Ca isotopic chain and in N = 82 nuclei. A concentration of electric dipole strength carrying a considerable part of the total E1 sum rule strength is obse
