Fusion and quasifission dynamics in the reactions Ca+Bk and Ti+Bk using TDHF
A. S. Umar, V. E. Oberacker, C. Simenel
Background: Synthesis of superheavy elements (SHE) with fusion-evaporation reactions is strongly hindered by the quasifission (QF) mechanism which prevents the formation of an equi…
Sensitivity of the fusion cross section to the density dependence of the symmetry energy
P. -G. Reinhard, A. S. Umar, P. D. Stevenson +3
It is the aim of this paper to discuss the impact of nuclear fusion on the EOS. This is a timely subject given the expected availability of increasingly exotic beams at rare isotop…
Quasifission dynamics in TDHF
A. S. Umar, V. E. Oberacker, C. Simenel
For light and medium mass systems the capture cross-section may be considered to be the same as that for complete fusion, whereas for heavy systems leading to superheavy formations…
Dynamics of quasifission
A. S. Umar, V. E. Oberacker, C. Simenel
Quasifission is the primary reaction mechanism that limits the formation of superheavy nuclei and consequently an important ingredient for choosing the best target-projectile combi…
Shape evolution and collective dynamics of quasifission in TDHF
A. S. Umar, V. E. Oberacker, C. Simenel
Background: At energies near the Coulomb barrier, capture reactions in heavy-ion collisions result either in fusion or in quasifission. The former produces a compound nucleus in st…
Swelling of nuclei embedded in neutron-gas and consequences for fusion
A. S. Umar, V. E. Oberacker, C. J. Horowitz +2
Fusion of very neutron rich nuclei may be important to determine the composition and heating of the crust of accreting neutron stars. We present an exploratory study of the effect…
