WebNov 18, 2024 · Yes, it's perfectly possible, but extremely unlikely. It can happen through direct resonances, as in p p ¯ → J / ψ → e + e −, or through virtual particles, as in p p ¯ → γ ∗ → e + e −. (Timescales for the intermediate state are much shorter than microseconds.) It doesn't happen very often because the proton and antiproton can ... WebThe reason that 2 H is vulnerable to disintegration by photons is that it consists of one neutron and one proton, which in the ground state have parallel spin (with I = l + 1 2, where l is the angular momentum quantum number and 1 2 is the spin). The anti-parallel level (I = l − 1 2) is an excited level which is unstable by about 65 keV [1], The electromagnetic field of …
