It is formed when a positive muon captures an atomic electron after being slowed down in matter.
In the process of electron capture, an inner-shell atomic electron is captured by the atomic nucleus, initiating the transformation of a nuclear proton into a neutron and lowering the atomic number by one unit (see radioactivity: Types of radioactivity).
Precise luminosity measurements for the OLYMPUS two-photon exchange experiment at DESY were performed by counting scattering events with alternating beams of electrons and positrons incident on atomic electrons in a gaseous hydrogen target.
However, it has been recently argued on theoretical grounds that in some cases, it is desirable to have an atomic size electron probe with customized aberrations [9].
We show that valley interference leads to orders of magnitude variations in electron exchange coupling when donor configurations are changed on an atomic scale.
Standard methods for the detection of gamma rays are based on the effects of the liberated atomic electrons in gases, crystals, and semiconductors (see radiation measurement and scintillation counter).
The program focuses in particular on the interactions of neutrinos scattering off atomic electrons in the detecting medium of liquid helium, resulting in recoil electrons which can be measured.
In practice, there is some difference in the case of an electron because of the indistinguishability of the incident and atomic electrons.
Photon interactions with tissue, such as photo-electric absorption, Compton scatter, and pair production, are dependent on the atomic number, electron density of the tissue, and photon energy.
When an electron moving in an atomic orbit is in a magnetic field B, the force exerted on the electron produces a small change in the orbital motion; the electron orbit precesses about the direction of B. As a result, each electron acquires an additional angular momentum that contributes to the magnetization of the sample.
