- Alikhanov "discovered that positrons were present even in the absence of a converter made from a heavy element, and this led him to the discovery of a new phenomenon—production of an electron-positron pair as a result of internal conversion of the energy of the excited nucleus."
- In particular, for high-energy photons, which mostly interact by electron–positron pair production, the radiation length is used much like the mean free path in radiography.
- The anomalous gamma-ray behavior was eventually ascribed to electron–positron pair production and annihilation.
- The photon must be near a nucleus in order to satisfy conservation of momentum, as an electron–positron pair produced in free space cannot satisfy conservation of both energy and momentum.
- The spark chamber was used to induce a process called electron-positron pair production as a gamma ray entered the telescope.
- The anomalous gamma-ray behavior was eventually ascribed to electron–positron pair production and annihilation.
- Supercritical atoms cannot be totally ionised because their 1s subshell would be filled by spontaneous pair creation in which an electron-positron pair is created from the negative continuum, with the electron being bound and the positron escaping.
- He authored papers on electron-positron pair production and (with Zel'dovich) statistical formulae in a Fermi gas.
- In such fields, an electron may gain an energy corresponding to the production of a new electron-positron pair, if it is transported over a distance given by the quantum mechanical uncertainty of its location : Δd= ƛ = ħ/mc.
- explodes because of the energy consumption arising from an electron-positron pair-production instability during the static O-burning stage, and is referred to as a pair-instability supernova (PISN).
- Followup observations by the SIGMA detector on board Granat showed that the object was a variable emitter of massive amounts of photon pairs at 511 keV, which usually indicates the annihilation of an electron-positron pair.
- For example, neutrinos should exhibit Bremsstrahlung in the form of electron-positron pair production.
- Euler was the first physicist who was able to show that Paul Dirac's introduction of the positron opens the possibility that photons in electron-positron pair production scatter with each other and calculated the cross section for this process in his PhD thesis.
- Furthermore, the annihilation (or decay) of an electron–positron pair into a "single" photon can occur in the presence of a third charged particle, to which the excess momentum can be transferred by a virtual photon from the electron or positron.
- The search looks for high-mass dilepton resonances: the Z′-boson would be produced by quark–antiquark annihilation and decay to an electron–positron pair or a pair of opposite-charged muons.
- In this sense, matter and antimatter particles (such as an electron and a positron) are identified beforehand.
- The experiment involves the creation of a special low-energy electron–positron collider, which will make it possible to observe the production of true muonium in collisions of electron and positron beams with an intersection angle of 75° with energies of 408 MeV.
- Bulanov proposed the idea of relativistic mirrors for generating X-rays, whereby a laser beam is reflected by plasma waves and is split up by nonlinear interactions to form a thin layer of relativistic electrons.
- He initiated the theory of non-local transport for heat flow in inertial confinement fusion, explained the collimation of laser-produced energetic electrons by resistively generated magnetic field, and with John G.
