When a positron and electron meet, they can annihilate, destroying both and converting their mass energy into two photons (or Z bosons, at high enough energy). This is why we don't see positrons very often.

Web3 apr. 2013 · In the first scientific report from the AMS, an experiment 18 years in the making that began taking data in May 2011, the collaboration presents a measurement of the “positron fraction,” the ratio of the number of positrons to the total number of electrons plus positrons, at energies between 0. 5 and 350 giga-electron-volts (GeV) (Fig. 1).
WebA positron has the same mass as that of an electron with an electrical charge of +1e and a spin of 12. It is the antiparticle of the electron. The mass of an electron and positron is the same and is equal to 9.1110- 31 kg. Whereas, whereas the … WebThe positron binding energy is typically Eion = 10–100 meV, indicating that positrons are thermally excited from these Rydberg states at 100–300 K. The hydrogenic positron state around a negative ion has a typical extension of 10–100 Å and thus positrons probe the same electron density as in the defect-free lattice.
