Coulomb Forces Scattering Amplitude on Its Residue
2011/7/20
Explicit expressions of the vertex constant for the decay of a nucleus into two charged particles for an arbitrary orbital momentum $l$ are derived for the standard expansion of the effective-range fu...
Momentum dependence of the symmetry potential and its influence on nuclear reactions
LQMD model ass splitting omentum-dependent potential
2011/7/20
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,...
