Atomic-number dependence of relativistic effects on chemical bonding

2000
Abstract The Atomic-number dependence of the relativistic effects on chemical bonding has been studied using the difference (ΔAPB) in the bond overlap populations between the relativistic and nonrelativistic DV-Xα calculations for various XH diatomic hydrides (XCu, Ag, and Au) and XF 6 hexafluorides (XS, Se, Mo, Ru, Rh, Te, W, Re, Os, Ir, Pt, U ...

Effective Atomic Numbers for Fe–Mn Alloy Using Transmission Experiment

Chinese Physics Letters, 2007
The effective atomic numbers (Zeff) and effective electron density (Ne) for Fe–Mn alloy with different Mn contents are calculated using the mass attenuation coefficients μ/ρ obtained via XCOM in the photon energy range of 1 keV–1 GeV. The results are compared with the values measured at the photon energy of 662, 1170 and 1332 keV.

Determination of the effective atomic numbers of light composite materials

2009 IEEE Intrumentation and Measurement Technology Conference, 2009
The analysis of physical and chemical characteristics of materials (composite or not) via the determination of change in the effective atomic number (Zeff) can be performed by measuring the relation between the intensities of γ-rays under coherent (Rayleigh) and inelastic (Compton) scattering.

Magic Numbers in Atomic Clusters: Energetic, Electronic and Structural Effects

1992
The subject of magic numbers in clusters has been one of long-standing interest since early observation of pronounced intensity anomalies seen in the mass spectral distributions of molecular and atomic systems (1–10). Early observations in the case of water (2,3)revealed a particularly stable entity involving 21 molecules bound to a proton, which was ...
