Shakeoff of the vacuum polarization in quasimolecular collisions of very heavy ions

Published

Journal Article

The theory of direct electron-positron pair production in the collision of heavy ions is formulated in the framework of the quasimolecular model. The pair production process acquires a collective nature for (Z1+Z2)>1 and can be understood as the shakeoff of the strong vacuum polarization cloud formed in the quasimolecule. The total cross section is, e.g., 76 b for Pb + Pb at Coulomb barrier energies. © 1977 The American Physical Society.
