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...

A Skyrme-type momentum-dependent nucleon-nucleon force distinguishing isospin effect is parameterized and further implemented in the Lanzhou Quantum Molecular Dynamics (LQMD) model for the first time,...
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...

In low-density nuclear matter which is relevant to the crust region of neutron stars and collapsing stage of supernovae, non-uniform structures called "nuclear pasta" are expected.
Solar Influence on Nuclear Decay Rates: Constraints from the MESSENGER Mission
stroparticle physics – nuclear reactions – Sun:particle emission

2011/10/12
We have analyzed Cs-137 decay data, obtained from a small sample onboard the MESSENGER spacecraft en route to Mercury, with the aim of setting limits on a possible correlation between nuclear decay ra...
Nuclear reaction rates and the primordial nucleosynthesis
Early Universe Nuclear reaction rates Big-Bang Nucleosynthesis
font style='font-size:12px;'>
2011/7/20
The theoretical predictions of the primordial abundances of elements in the big-bang nucleosynthesis (BBN) are dominated by uncertainties in the input nuclear reaction rates. We investigate the effect...
