Determination of color centers in CaF2 crystals by multiple gamma-ray irradiations

Improving the Nutritional Value of Sunflower Meal by Electron Beam and Gamma Ray Irradiations

This research was performed to compare electron beam (EB) and gamma ray (GR) treatments at doses of 25, 50 and 75 kilo Gray (kGy) on ruminal degradation kinetics and in vitro digestibility of sunflower meal (SFM). Ionizing radiations of EB and GR had significant effects )P

Radiation-induced color centers in La-doped PbWO 4 crystals

This report presents the result of a study on radiation-induced color center densities in La-doped lead tungstate (PbWO 4 ) crystals. The creation and annihilation constants of radiation-induced color centers were determined by using transmittance data measured for a PbWO 4 sample before and during 60Co c-ray irradiation at a dose rate of 15 rad/h. Following a model of color center kinetics, th...

Energy transfer among color centers in LiF crystals

In colored LiF crystals there are many absorption and emission bands which cover a wide region of the spectrum from 200 up to 1 300 nm without breaking the continuity. In the frame of these favourable conditions we have performed some experiments of energy transfer among various color centers. The results indicate the existence of efficient exchanges of radiative energy among several bands by u...
