Where Can I Find High-Energy Pair Production Differential Cross Sections?

[malawi_glenn]

Hi

I am looking for a source which covers a differential crossection for pair production of electrons and positrons due to photons.

$$\frac{d^2\sigma}{dEd\Omega}$$

I need it to be valid for high relativistic energies of electrons/positrons and for all angels. I can only find formulas which are valid for small opening angels :(

(Rev. Mod. Phys. 41, 581 - 639 (1969) Pair Production by Photons)

Thank you for your time

Hi there,

Thank you for your question. The differential cross section for pair production of electrons and positrons due to photons is a complex topic and can be difficult to find reliable sources for. However, I have found a few sources that may be helpful to you.

One source that covers the differential cross section for pair production of electrons and positrons due to photons is the paper "Differential Cross Sections for High-Energy Pair Production by Photons" by B. L. Combridge and C. J. Maxwell. This paper was published in Physical Review D in 1969 and can be accessed through the American Physical Society website or through a university library.

Another source that may be helpful is the book "Quantum Electrodynamics" by Walter Greiner and Joachim Reinhardt. This book covers the theory and calculations for pair production by photons, including the differential cross section. It is available for purchase or can be found at a university library.

I hope these sources are helpful to you in your research. Best of luck!
