Beta Absorption Experiments with Geiger Counters
The absorption of electrons emitted by a beta radioactive source through different materials may be investigated by means of a Geiger counter....
-
Linear Absorption
As the extinction coefficient of matter gets significantly large, the electromagnetic radiation is absorbed by the solid. In the subsequent sections,...

Combining 3DXRD and Absorption Contrast Tomography
The 3DXRD setup sketched in Fig. 3.1 is very similar to the setup typically used for absorption contrast x-ray tomography at synchrotrons....

Absorption- and Phase-Based Imaging Signals for Neutron Tomography
Thermal and cold neutrons are a perfect tool to investigate massive and large (several cm3) samples by means of computerized tomography (CT). The...

Absorption of Light Waves (and EPWs) in Plasmas
This chapter discusses the absorption of light waves (and to a lesser extent, plasma waves) in plasmas. The collisional absorption coefficient of...

Quantum Theory of X-Ray Absorption Spectroscopy
As the first application of the Kramers-Heisenberg-Dirac theory we discuss the quantitative calculation of the x-ray absorption rate and cross...

Plasmon Induced Enhanced Nonlinear Absorption in Vanadium Disulfide-Silver Nanocomposite
This study presents a novel vanadium disulfide-silver nanocomposite synthesized through liquid phase exfoliation, demonstrating a six-fold...

Absorption Line Survey of H+3 Towards the Galactic Center
We have conducted high-resolution (R = 20,000) spectroscopy toward sources in the Galactic center in search of absorption lines of H+3. The...

The Dispersion and Absorption of Electromagnetic Waves
In this chapter the electromagnetic dispersion and absorption of real media are derived. First the phenomenology is introduced. Then, from the motion...

Non-linear Absorption
Non-linear absorption is mostly referred to wide-band gap materials, as dielectrics and semiconductors. There, the free-electron charge density...

Water Molecule Absorption Line Intensities in the IR Spectral Region
AbstractH 2 O absorption lines broadened by air pressure were recorded at an IFS 125HR Fourier spectrometer in the 3000–7500 cm −1 spectral region. The...

Molecular Hydrogen Absorption Line Detected in Dense Molecular Clouds
The H2 ν=0–1 S(0) absorption line was detected together with CO ν=0–2 toward NGC 7538 IRS1 using IRCS at Subaru Telescope. The H2/CO ratio are...

Probing the Circumgalactic Medium with X-ray Absorption Lines
The circumgalactic medium (CGM) fills the dark matter halo of a galaxy, serving as a gas reservoir between the intergalactic medium and the stellar...
