K. Dietz et M. Probsting, THE STRUCTURE OF THE QED VACUUM AND ELECTRON-POSITRON PAIR PRODUCTIONIN SUPERINTENSE, PULSED-LASER FIELDS, Journal of physics. B, Atomic molecular and optical physics, 31(8), 1998, pp. 409-414
We discuss electron-positron pair production by super-intense, short l
aser pulses off the physical vacuum state locally deformed by (strippe
d) nuclei with large nuclear charges. Consequences of non-perturbative
vacuum polarization resulting from such a deformation are briefly bro
ached. Production probabilities per pulse are calculated.
