Publikováno v: Physical Review C. 100
Background: The influence of inelastic excitations on sub-barrier fusion enhancement is well established; however, the transfer channel effect can be surprising. Recently, it has been shown that the $2n$ transfer channel is mainly responsible for sub

In collisions of light, stable, weakly bound nuclides, complete fusion (capture of all of the projectile charge) has been found to be suppressed by $\ensuremath{\sim}30%$ at above-barrier energies. This is thought to be related to their low threshold

The atomic numbers and the masses of fragments formed in quasi-fission reactions have been simultaneously measured at scission in 48 Ti + 238 U reactions at a laboratory energy of 286 MeV. The atomic numbers were determined from measured characterist

Competition between Fusion and Quasi-fission in the Formation of Super-heavy Elements

Publikováno v: Proceedings of The 26th International Nuclear Physics Conference — PoS(INPC2016).
Quasifission is a non-equilibrium dynamical process resulting in rapid separation of the dinuclear system initially formed after capture and sticking of two colliding heavy nuclei. This can inhibit fusion by many orders of magnitude, thus suppressing
