Abstract
In the present work, a group of four glass samples that have chemical composition of [(35-x) B2O3-20TeO2-10GeO2-35MgO-xLa2O3] were x values varies from 2.5 to 10 all in mol percentage, which fabricated using ordinary melting then quenching technique. Many physical and mechanical have been measured and calculated like: density, packing density, internuclear distance (ri), oxygen packing density (OPD), oxygen molar volume (OMV), dissociation energy (Gt), packing density (Vt), Poisson ratio (σ), fractal bond connectivity (d), elastic modulus. The behavior of the La10 was examined using XRD in the range of 10–80°. The UV–visible spectrum of absorption of the La2.5, La5, La7.5, and La10 glasses were measured. Several optical parameters have been calculated and extracted including the cutoff wavelength, Urbach's energy (EU), dielectric constant (ε), refractive index (n), molar refraction (RM), reflection loss (RL), molar electron polarizability (αM), Optical transmission (T), Optical basicity (Λ), and Metallization criteria (M). Various noticeable bands vibration of boron units structural besides the modes of vibration of that effected by adding metal cations were studied using FTIR to analyze different structure groups like: BO3 triangles, BO4 pyramids, tetragonal TeO4 pyramids, and trigonal TeO3 pyramids. Using Monte Carlo simulation, the MAC of glass materials was evaluated in the current work. Various radiation shielding parameters were investigated at low and high energies.
期刊介绍：
Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field.
Please note the following:
1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy.
2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc.
3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
