Measurement of effective atomic number and electron density using an EMI scanner

Neuroradiology, 1976
Computed tomography, employing an EMI scanner at two beam energies, can be used to obtain information about the electron density and the effective atomic number of materials. The theory which is discussed has been verified experimentally and then applied in the investigation of some brain tumours in vivo.

Effective atomic number and density determination of rocks by X-ray microtomography

Micron, 2015
Microtomography, as a non-destructive technique, has become an important tool in studies of internal properties of materials. Recently, interest using this methodology in characterizing the samples with respect to their compositions, especially rocks, has grown.

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.

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 ...
