Theoretical considerations about heavy-ion fusion in potential scattering
L. F. Canto, R. Donangelo, M. S. Hussein +3
We carefully compare the one-dimensional WKB barrier tunneling model, and the one-channel Schödinger equation with a complex optical potential calculation of heavy-ion fusion, for…
Inclusive Breakup Theory of Three-Body Halos
M. S. Hussein, L. A. Souza, E. Chimanski +2
We present a recently developed theory for the inclusive breakup of three-fragment projectiles within a four-body spectator model \cite{CarPLB2017}, for the treatment of the elasti…
Approximate transmission coefficients in heavy ion fusion
A. J. Toubiana, L. F. Canto, M. S. Hussein
In this paper we revisit the one-dimensional tunnelling problem. We consider different approximations for the transmission through the Coulomb barrier in heavy ion collisions at ne…
Dipole-dipole dispersion interactions between neutrons
James F. Babb, Renato Higa, Mahir S. Hussein
We investigate the long-range interactions between two neutrons utilizing recent data on the neutron static and dynamic electric and magnetic dipole polarizabilities. The resulting…
Inclusive breakup of Borromean nuclei
Mahir S. Hussein, Brett V. Carlson, Tobias Frederico
We derive the inclusive breakup cross section of a three-fragment projectile nuclei, , in the spectator model. The resulting four-body cross section for observing…
van der Waals and Casimir-Polder interactions between neutrons
James F. Babb, Mahir S. Hussein
We investigate the van der Waals interaction between neutrons using the theory of Casimir and Polder, wherein the potential for asymptotically large separations falls off as the in…
Disappearance of Mott oscillations in sub-barrier elastic scattering of identical nuclei and atomic ions
M. S. Hussein, L. F. Canto, R. Donangelo +1
The scattering of identical nuclei at low energies exhibits conspicuous Mott oscillations which can be used to investigate the presence of components in the predominantly Coulomb i…
Theoretical study of the elastic breakup of weakly bound nuclei at near barrier energies
D. R. Otomar, P. R. S. Gomes, J. Lubian +2
We have performed CDCC calculations for collisions of Li projectiles on Co, Sm and Pb targets at near-barrier energies, to assess the importance of the…
A consistent four-body CDCC model of low-energy reactions: Application to 9Be + 208Pb
M. S. Hussein, P. Descouvemont, L. F. Canto
We investigate the Be + Pb elastic scattering, breakup and fusion at energies around the Coulomb barrier. The three processes are described simultaneously, with identic…
Current Status of Nuclear Physics Research
C. A. Bertulani, M. S. Hussein
In this review we discuss the current status of research in nuclear physics which is being carried out in different centers in the World. For this purpose we supply a short account…
Four-body effects on 9Be + 208Pb scattering and fusion around the Coulomb barrier
P. Descouvemont, T. Druet, L. F. Canto +1
We investigate the 9Be + 208Pb elastic scattering and fusion at energies around the Coulomb barrier. The Be nucleus is described in a α+ α+ n three-body model, using the hypers…
Disappearance of Mott oscillations in sub-barrier elastic scattering of identical heavy ions and the nuclear interaction
L. F. Canto, M. S. Hussein, W. Mittig
We investigate the possible disappearance of Mott oscillations in the scattering of bosonic nuclei at sub-barrier energies. This effect is universal and happens at a critical value…
Assessing the adequacy of the bare optical potential in near-barrier fusion calculation
L. F. Canto, P. R. S. Gomes, J. Lubian +2
We critically examine the differences among the different bare nuclear interactions used in near-barrier heavy ion fusion analysis and Coupled-Channels calculations, and discuss th…
Scaling laws for near barrier Coulomb and Nuclear Breakup

We investigate the nuclear and the Coulomb contributions to the breakup cross sections of Li in collisions with targets in different mass ranges. Comparing cross sections for d…
Toward a microscopic description of reactions involving exotic nuclei
P. Descouvemont, M. S. Hussein
We propose an extension of the Continuum Discretized Coupled Channels (CDCC) method, where the projectile is described by a microscopic cluster model. This microscopic generalizati…
Complete Fusion of Weakly Bound Cluster-Type Nuclei at Near Barrier Energies
M. S. Hussein, P. R. S. Gomes, J. Lubian +2
We consider the influence of breakup channels on the complete fusion of weakly bound cluster-type systems in terms of dynamic polarization potentials. It is argued that the enhance…
The nuclear and Coulomb breakup of the weakly bound Li with targets in the range from A = 59 to 208
D. R. Otomar, P. R. S. Gomes, J. Lubian +2
We have performed CDCC calculations for the Li + Co, Sm and Pb systems, to investigate the dependence of the relative importance of nuclear and Coulomb…
A Relativistic Separable Potential to Describe Pairing in Nuclear Matter

Using the Dirac-Hartree-Fock-Bogoliubov approximation to study nuclear pairing, we have found the short-range correlations of the Dirac S pairing fields to be essentially i…
