Neutrino scattering on atomic electrons in searches for neutrino magnetic moment

, 2010
The scattering of a neutrino on atomic electrons is considered in the situation where the energy transferred to the electrons is comparable to the characteristic atomic energies, as relevant to the current experimental search for neutrino magnetic moment.

A Comment on the Strong Interactions of Color-Neutral Technibaryons

, 1992
We estimate the cross section for the scattering of a slow, color-neutral technibaryon made of colored constituents with nuclei. We find a cross section of order $A^2\ 10^{-45}$ cm$^2$, where $A$ is the atomic number of the nucleus. Even if technibaryons

Antiproton-Hydrogen annihilation at sub-kelvin temperatures [PDF]

, 1998
The main properties of the interaction of ultra low-energy antiprotons ($% E\le10^{-6}$ a.u.) with atomic hydrogen are established. They include the elastic and inelastic cross sections and Protonium (Pn) formation spectrum.

Simulated Photoabsorption Spectra for Singly and Multiply Charged Ions

Atoms
Simulated (or measured) photoabsorption spectra often provide the first indication of how matter interacts with light when irradiated by some radiation source. In addition to the direct, often slowly varying photoabsorption cross-section as a function of
