The threshold energy should not be confused with the threshold displacement energy, which is the minimum energy needed to permanently displace an atom in a crystal to produce a crystal defect in radiation material science.
The threshold displacement energy is a materials property relevant during high-energy particle radiation of materials. The maximum energy that an irradiating particle can transfer in a binary collision to an atom in a material is given by (including relativistic effects)
The pion production process continues until the cosmic ray energy falls below the threshold for pion production. Due to the mean path associated with this interaction, extragalactic cosmic ray protons traveling over distances larger than 50 Mpc (163 Mly) and with energies greater than the threshold should never be observed on Earth. This ...
The IBD reaction can only be initiated when the antineutrino possesses at least 1.806 MeV [3] [4] of kinetic energy (called the threshold energy). This threshold energy is due to a difference in mass between the products (e + and n) and the reactants (ν e and p) and also slightly due to a relativistic mass effect on the antineutrino. Most of ...
A modification of canonical variational transition state theory in which, for energies below the threshold energy, the position of the dividing surface is taken to be that of the microcanonical threshold energy. This forces the contributions to rate constants to be zero if they are below the threshold energy.
As energy must be conserved, for pair production to occur, the incoming energy of the photon must be above a threshold of at least the total rest mass energy of the two particles created. (As the electron is the lightest, hence, lowest mass/energy, elementary particle, it requires the least energetic photons of all possible pair-production ...
Luckily, core CPI, which excludes more volatile food and energy prices and is a key indicator of inflation, then came in lighter than expected, which sent Treasury yields tumbling lower, much to ...
Cherenkov threshold detectors have been used for fast timing and time of flight measurements in particle detectors. More elaborate designs use the amount of light produced. Recording light from both primary and secondary particles, for a Cherenkov calorimeter the total light yield is proportional to the incident particle energy.
