Using TDHF to Study Quasifission Dynamics [Book Chapter]

Other Umar, A. S. ; Simenel, C.

We show that the microscopic TDHF approach provides an important tool to shed some light on the nuclear dynamics leading to the formation of superheavy elements. In particular, we discuss studying quasifission dynamics and calculating ingredients for compound nucleus formation probability calculations.

Time-dependent mean-field investigations of the quasifission process

Journal Article Umar, A. S. ; Simenel, C. ; Ayik, S. - EPJ Web of Conferences

We demonstrate that the microscopic Time-dependent Hartree-Fock (TDHF) theory provides an important approach to shed light on the nuclear dynamics leading to the formation of superheavy elements. In particular, we discuss studying quasifission dynamics and calculating ingredients for compound nucleus formation probability calculations. We also discuss possible extensions to TDHF to address the distribution of observables.

TDHF Investigations of the U+U Quasifission Process

Journal Article Umar, A. S. ; Simenel, C. - Acta Physica Polonica. Series B

The use of actinide collisions have been suggested as a way to produce neutron-rich isotopes of high-Z nuclei. The collision dynamics of these reactions can be studied using unrestricted time-dependent Hartree–Fock (TDHF) calculations. Here, we report on the recent studies of quasifission for the ²³⁸U+ ²³⁸U system.
