Noun
an elementary particle with positive charge; interaction of a positron and an electron results in annihilation
Source: WordNetAlso observed, for charged pions only, is the very rare "pion beta decay " (with branching fraction of about 10 −8 ) into a neutral pion, an electron and an electron antineutrino (or for positive pions, a neutral pion, a positron, and electron neutrino). Source: Internet
An unfilled state in the Fermi sea behaves like a positively charged electron, though it is referred to as a "hole" rather than a "positron". Source: Internet
At the Jülich Institute of Neurosciences and Biophysics, the world's largest PET-MRI device began operation in April 2009: a 9.4- tesla magnetic resonance tomograph (MRT) combined with a positron emission tomograph (PET). Source: Internet
A positron (e + )—an antimatter electron—is emitted along with an electron neutrino The number of protons and neutrons in the atomic nucleus can be modified, although this can require very high energies because of the strong force. Source: Internet
Because charge must be conserved, one of the products of muon decay is always an electron of the same charge as the muon (a positron if it is a positive muon). Source: Internet
Best results come from the Super-Kamiokande water Cherenkov radiation detector in Japan. 2015 analysis gave half-life higher than main years via positron decay http://arxiv. Source: Internet
