A self-consistent perburbation theory to calculate magnetoresistivity, susceptibility, and the Hall constant for the crystal field split cerium based systems is employed. In this theory, excitonic and other correlations ...

Self-consistent perturbation theory is employed for the calculation of physical quantities in mixed valence systems. A single impurity U -> infinity Anderson model is considered with and without crystalline field splitting. ...

Neutron diffraction techniques have been employed to obtain an accurate high-resolution real space correlation function for vitreous GeO2. The GeO bond length is found to be 1.739 + and the rms bond length variation 0.048 ...

Surface-enhanced Raman scattering has recently become a powerful vibrational spectroscopic tool for numerous applications in physical, chemical, biological as well as medical science. Apart from a chemical enhancement ...
