Nuclear structure in strong magnetic fields: nuclei in the crust of a magnetar
Nuclear structure strong magnetic fields: nuclei crust magnetar
font style='font-size:12px;'>
2011/10/14
Covariant density functional theory is used to study the effect of strong magnetic fields, up to the limit predicted for neutron stars (for magnetars $B \approx10^{18}$G), on nuclear structure. All ne...

2011/7/21
The activation cross sections of (d,p), (d,2n), (d,3n), and (d,2p) reactions on 63,65Cu were measured in the energy range from 4 to 20 MeV using the stacked-foils technique.
Leading twist nuclear shadowing phenomena in hard processes with nuclei
shadowing phenomena hard processes nuclei
font style='font-size:12px;'>
2011/7/21
We present and discuss the theory and phenomenology of the leading twist theory of nuclear shadowing which is based on the combination of the generalization of Gribov-Glauber theory, QCD factorization...
Long-term evolution of massive black hole binaries. IV. Mergers of galaxies with collisionally relaxed nuclei
large-scale structure of Universe – cosmology: theory – cosmology: observations – cosmological parameters
font style='font-size:12px;'>
2011/10/12
We simulate mergers between galaxies containing collisionally-relaxed nuclei around massive black holes (MBHs). Our galaxies contain four mass groups, representative of old stellar populations; a prim...
Nuclear dynamics at the balance energy of mass asymmetric colliding nuclei
heavy-ion collisions uantum molecular dynamics (QMD) model
font style='font-size:12px;'>
2011/7/20
Using the quantum molecular dynamics model, we study the nuclear dynamics at the balance energy of mass asymmetric colliding nuclei by keeping the total mass of the system fixed as 40, 80, 160, and 24...
Multifragmentation at the balance energy of mass asymmetric colliding nuclei
asymmetric colliding nuclei balance energy
font style='font-size:12px;'>
2011/7/20
Using the quantum molecular dynamics model, we study the role of mass asymmetry of colliding nuclei on the fragmentation at the balance energy and on its mass dependence. The study is done by keeping ...
Alpha-Cluster Model, Charge Symmetry of Nuclear Force and Single Particle Bound State Potential in Symmetrical Nuclei
Alpha-Cluster Model Nuclear Force Bound State Potential
font style='font-size:12px;'>
2011/7/20
A phenomenological alpha-cluster model based on the charge symmetry of nuclear force allows one to estimate the last proton position radius (LPPR) in a symmetrical nucleus. The values of LPPR obtained...

2011/7/20
The concept of heavy particle radioactivity (HPR) is changed to allow emitted particles with Z_e>28 from parents with Z>110 and daughter around 208Pb.
Relativistic Description of Finite Nuclei Based on Realistic $NN$ Interactions
