Question: Calculate the energy threshold (E ) for the photon conversion into e + e - pair in the electric field of (1) an oxygen

Calculate the energy threshold (E_γ) 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 m_ee> 0. In which on figuration is m_ee a minimum? Consider in particular electron energies E₊, E_– >> m_e.
