The incorporation of Bi
2 O3 in the Bi2 O3 –BaO–V2 O5 (BBV) glasses leads to higher density and molar volume. The average cross-link density ( n ¯ c ) increases from 4.2 to 4.8 cm−3 whereas the number of bonds per unit volume (nb ) decreases from 4.974 × 1022 to 4.753 × 1022 as Bi2 O3 is incorporated into the BBV glasses. The high values of elastic moduli indicate that the present glasses are resistant to any kind of the deformations when subjected to any kind of forces. The fractal bond connectivity (d) values indicate the 2D structure of the present glasses. Using Phy-X software, the radiation shielding capabilities were studied when Bi2 O3 was used in place of BaO. The authors determined the linear attenuation coefficient (LAC) and discussed the change in this parameter due to the addition of Bi2 O3 to the glasses. The glass with 20 mol% of Bi2 O3 has the highest LAC and also has the highest effective atomic number. The minimum half value layer values was reported at 0.284 MeV and are equal to 1.220, 0.964 and 0.691 cm for the glasses with 5, 10 and 20 mol% of Bi2 O3 respectively. The HVL increases with increasing energy, indicating that the samples are more efficient at shielding the low-energy radiation. At 0.347 MeV, the Zeff values are equal to 18.16, 21.09 and 26.05 for the samples with 5, 10 and 20 mol% of Bi2 O3 respectively. The tenth value layer decreased with increasing density; for example, at 0.511 MeV, the layer decreased from 6.886 to 4.887 cm as the density increased from 3.6 to 4.281 g/cm3 . The mean free path (MFP) was calculated and compared at 0.284 MeV. The authors found that BBV3 has the smallest MFP (0.997 cm) of the three examined glasses. [ABSTRACT FROM AUTHOR]- Published
