Time-dependent Hartree-Fock studies of superheavy molecules

The time dependent Hartree-Fock approximation is used to study the dynamical formation of long-lived superheavy nuclear complexes. The effects of long-range Coulomb polarization are treated in terms of a classical quadrupole polarization model. Our calculations show the existence of "resonantlike" structures over a narrow range of bombarding energies near the Coulomb barrier. Calculations of ²³⁸U + ²³⁸U are presented and the consequences of these results for supercritical positron emission are discussed.NUCLEAR REACTIONS ²³⁸U + ²³⁸U collisions as a function of bombarding energy, in the time-dependent Hartree-Fock approximation.
