Calculation of electron-positron production in supercritical uranium-uranium collisions near the Coulomb barrier
Edward Ackad, Marko Horbatsch
The time-dependent Dirac equation was solved for zero-impact-parameter bare U-U collisions in the monopole approximation using a mapped Fourier grid matrix representation. A total…

Calculation of supercritical Dirac resonances in heavy-ion collisions
Edward Ackad
This resonance is similar in character to other resonances in atomic physics. It is parameterized by its energy and its lifetime. A numerical discretization technique, the mapped F…

Supercritical Dirac resonance parameters from extrapolated analytic continuation methods
Edward Ackad, Marko Horbatsch
The analytic continuation methods of complex scaling (CS), smooth exterior scaling (SES), and complex absorbing potential (CAP) are investigated for the supercritical quasimolecula…
