Calculate the energy threshold (E ) for the photon conversion into e + e - pair
Question:
Calculate the energy threshold (Eγ) for the photon conversion into e+e- pair in the electric field of (1) an oxygen nucleus, (2) an electron and (3) for the post production of a μ+μ- pair in the field of a proton. In any case the photon, which has mass equal to zero converts in a pair of mass mee > 0. In which on figuration is mee a minimum? Consider in particular electron energies E+, E– >> me.
