PCN calculations for Z=111 to Z=118Jul 01 2019In previous publications, we presented evidence for the importance of spin in determining capture and evaporation residue cross sections in the synthesis of heavy nuclei. We extend the previous calculations which dealt with nuclei where ZCN is less than ... More
Fission modes in fermium isotopes with Brownian shape-motion modelJul 01 2019Fission-fragment mass and total-kinetic-energy distributions following fission of the fermium isotopes $^{256,258,260}\text{Fm}$ at low excitation energy have been calculated using the Brownian shape-motion model. A transition from asymmetric fission ... More
Fluid Dynamics Study of the $Λ$ Polarization for Au+Au Collisions at $\sqrt{s_{NN}}=200$ GeVJul 01 2019With a Yang-Mills field, stratified shear flow initial state and a high resolution (3+1)D Particle-in-Cell Relativistic (PICR) hydrodynamic model, we calculate the $\Lambda$ polarization for peripheral Au+Au collisions at RHIC energy of $\sqrt{S_{NN}}=200$ ...

Pseudo-spin symmetry restoration and the in-medium balance between nuclear attractive and repulsive interactionsJul 01 2019The mechanism that restores the pseudo-spin symmetry (PSS) are investigated under the relativistic Hartree-Fock (RHF) approach, by focusing on the in-medium balance between nuclear attractive and repulsive interactions. It is illustrated that the modelings ... More
Low Energy Magnetic Radiation (LEMAR ) of Warm NucleiJun 30 2019The enhancement observed below 2 MeV in the radiative strength function of nuclei near closed shells is explained by shell model calculations as M1 transitions between excited states. In the open-shell a change to a bimodal structure composed of the zero ... More
