چکیده
We consider the electron-positron pair production by a photon in Coulomb field near threshold. obtain analytical results for particle energy spectrum and angular distribution exactly parameter $Ze^2/\hbar v$. show that Furry-Sommerfeld-Maue approximation wave functions used Nishina, Tomonaga Sakata is not sufficient leads to wrong results.

0 η ′ photoproduction near threshold
In this work, the η meson photoproduction near threshold is studied in the quark model framework. A pseudovector effective Lagrangian is introduced for the ηNN coupling and the newly published data from the SAPHIR Collaboration provide good constraints to this parameter. Corrections of order O(1/m2q) for the electromagnetic interaction vertex are taken into account, which produce corrections of...

متن کاملThe A-Dependence of J/ψ Photoproduction Near Threshold
The primary goal of this experiment in Hall C is the measurement of the Adependence of quasi-free J/ψ photoproduction with an average photon energy near 11 GeV. Analysis of these data will permit a greatly improved determination of the fundamental J/ψ-nucleon total cross section. In order to reduce modeling uncertainties, we will also make precision measurements of the (s, t) dependence of the ...
متن کاملω-Meson Photoproduction on Nucleons In the Near Threshold Region
The ω-meson photoproduction, γ+p → p+ω, is studied in the framework of a model, containing π-meson exchange in t-channel and nucleon-exchange in sand u-channels. Considering both ωNN -coupling constants in the region of time-like meson four momenta as the free parameters, we find different sets of solutions for these constants from the existing data on the t-dependence of the differential cross...
متن کاملFinal State Interactions in Ω Photoproduction near Threshold Yongseok Oh
Vector meson photoproduction and electroproduction have been suggested as a tool to find or confirm the nucleon resonances. In order to extract more reliable informations on the nucleon resonances, understanding the non-resonant background is indispensable. We consider final state interactions in ω photoproduction as a background production mechanism. For the intermediate states, we consider nu...
