The nuclear rainbow, observed in the elastic α-nucleus and light heavy-ion (HI) scattering at medium energies, is proven to be due to the refraction of the incident wave by the attractive nucleus-nucleus optical potential. The rainbow pattern is usually associated with a broad oscillation of the Airy minima in elastic scattering cross section, as a result of an interference of the refracted...
We study multistrange Ca, Sn and Pb hypernuclei with $\Lambda\Lambda$ pairing correlations by using the multidimensionally-constraint relativistic Hartree-Bogoliubov (MDC-RHB) model. The axial deformation is allowed and the $\Lambda\Lambda\omega$-tensor coupling is included to reproduce the small spin-orbit splittings for $\Lambda$ hyperon. The separable pairing force of finite-range form is...
By involving the constraints of the slope of nuclear symmetry energy L into the question of determination of the high-density symmetry energy, one needs to probe the curvature of nuclear symmetry energy $K_{sym}$. Based on the Isospin-dependent Boltzmann-Uehling-Uhlenbeck (IBUU) transport model, effects of the curvature of nuclear symmetry energy on the squeezed-out nucleons are demonstrated...
To reach heavy neutron rich nuclei region and superheavy stability island, multinucleon transfer reaction is the most possible way, which has been investigated within dinuclear system model. The calculated transfer cross sections can reproduce the experimental data nicely. The transfer dynamics in the reaction of $^{124,132}$ Sn+$^{238}$ U/$^{248}$ Cm near Coulomb barrier energies is...
nuclear fission is a large amplitude collective motion. It is particularly important in the areas of energy production and nuclear waste disposal. Microsopic study of fission phenomenon is a truly predictive theory. We use the TDHF method to study the fission process after the fission barrier. we compare the fission process and fission fragment disturbution at different inital deformation...
The ($p,n$) reaction at intermediate energies (about 200MeV) is a very effective tool to investigate spin-isospin excitations in nuclei. Gamow-Teller (GT) states is one of the most basic spin-isospin excitations. GT states are changed spin and isospin of the nuclei by one unit without being changed the orbital angular momentum from the initial quantum state. Fermi states are also one of the...
Nuclear mass plays an essential role in the understanding of the r-process which is responsible for the synthesis of about one-half of elements heavier than iron up to bismuth and all of thorium and uranium. The nuclei around the doubly magic numbers N=50, N=82 and N=126 are believed to be waiting points were matter accumulate and therefore form the major peaks in the r-process abundance....
