Low and medium energy deuteron-ind ced reactions on $^{63,65}$Cu nuclei
Low medium energy deuteron-ind ced reactions
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
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...
Nuclear dynamics at the balance energy of mass asymmetric colliding nuclei
heavy-ion collisions uantum molecular dynamics (QMD) model
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
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
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...

superheavy nuclei Heavy particle radioactivities
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
$NN$ Interactions
2011/7/20
A set of relativistic mean field models is constructed including the Hartree and Hartree-Fock approximation accounting for the exchange of isoscalar and isovector mesons as well as the pion.

J-Projected Hartree-Fock Model Nuclei Electromagnetic Transitions
2011/7/20
Rotational structures of even-even $^{148-160}$Nd nuclei are studied with the self-consistent deformed Hartree-Fock (HF) and angular momentum (J) projection model. Spectra of ground band, recently obs...

Spin Scissors Mode M1 States Fine Structure
2011/7/20
The coupled dynamics of low lying modes, including the scissors mode, and various giant quadrupole resonances are studied with the help of the Wigner Function Moments method generalized to take into a...
