In this work, were determined some radiation shielding and dosimetric parameters of three types of bricks for photons energy from 1 keV to 100 GeV photons using the Phy-X/PSD software, and for comparison also has been calculated the same parameters f

INEGI reports that 81% of new constructions are built with durable materials, such as concrete blocks, including rooms where ionizing radiation is used, such as clinics and hospitals. The volume ratios used in the manufacture of concrete blocks have

A Raman system, with the 514.5 and 632.8 nm excitations wavelengths, was used to qualitatively detect the surface roughness of a CdS wafer sample. Anti-Stokes Raman spectra were obtained from several sample zones with different mean roughness levels,

Terahertz absorbance in (001) ZnSe has been experimentally studied using a femtosecond (fs) pulse train emitted from a self mode lock fiber laser. Preliminary results suggest three different regions for the phase and two different behaviors. The Drud

A micro-Raman system is used to study the β-carotene of dry and fresh carrot samples in environments with variations of the temperature between 16 o C and 120 o C. It is shown that the Raman peaks intensities of the dry sample diminish considerably,

A Raman spectroscopic study was performed to detect the surface roughness of a cadmium telluride (CdTe) wafer sample, using the 514.5, 632.8 and 830.0 nm excitations wavelengths. To verify the relation between the roughness and the structure of Raman

This note compares experimental reflectivity values of CdTe with those calculated from the corrected equation in a previous comment, which replaced a wrongly typed equation in three previously published papers.

In this work, we show that the shape line of the Raman spectra of CdTe for a small mean roughness, measured with an excitation wavelength near to the critical point E0, depends on the acoustic modes. The application of the spatial correlation model s
