“…For example, the radii of neutron stars are related to the pressure of isospin asymmetric nuclear matter, which is proportional to the slope of the symmetry energy [4]. Additionally, the proton fraction as a function of density for a neutron star in β equilibrium has been shown to be very sensitive to the density dependence of the symmetry energy, E sym (ρ) [5,6]. The proton fraction of the neutron star, and therefore E sym (ρ), defines whether the neutron star will cool quickly through the direct URCA process or more slowly through the standard URCA process.…”

The NIMROD-ISiS array was used to study the In order to explore the model dependence of the results, the antisymmetrized molecular dynamics, constrained molecular dynamics, and stochastic mean field models were each compared to the experimental results to extract information on the form of the symmetry energy. The results demonstrate that sensitivity of the models to the nuclear Equation of State can vary significantly based on the treatment of the nuclear dynamics. Despite the differences in the sensitivity, improved agreement with the experimental data is observed for each model with a stiff density dependence of the symmetry energy.

“…Recent experimental results are being used to apply constraints to the asymmetric part of the EoS, or density dependence of the symmetry energy (E sym (ρ)) [3][4][5][6]. Constraining the density dependence of the symmetry energy is essential for understanding the fundamental nucleon-nucleon interaction and has important astrophysical implications [3,5,[7][8][9][10][11][12][13].…”

“…Differences between the free neutron and free proton transverse collective flows have been predicted to be strongly sensitive to E sym (ρ) [43][44][45]. However, obtaining accurate energy and angular measurements of free neutrons, along with charged particles, is a difficult task.…”

The transverse flow and relative mid-rapidity yield of isotopically identified light charged particles (LCPs) Ni systems. A large enhancement of the mid-rapidity yield of the LCPs was observed relative to the yield near the projectile rapidity. In particular, this enhancement was increased for the more neutron-rich LCPs demonstrating a preference for the production of neutron-rich fragments in the mid-rapidity region. Additionally, the transverse flow of the LCPs was extracted which provides insight into the average movement of the particles in the mid-rapidity region. Isotopic and isobaric effects were observed in the transverse flow of the fragments. In both cases, the transverse flow was shown to decrease with an increasing neutron content in the fragments. A clear inverse relationship between the transverse flow and relative mid-rapidity yield is shown. The increased relative mid-rapidity emission produces a decreased transverse flow. The Stochastic Mean-Field model was used for comparison to the experimental data. The results showed that the model was able to reproduce the general isotopic and isobaric trends for the mid-rapidity emission and transverse flow. The sensitivity of these observables to the density dependence of the symmetry energy was explored. The results indicate that the transverse flow and mid-rapidity emission of the LCPs are sensitive to the denisty dependence of the symmetry energy.

Due to their excellent electrical insulation properties and processability, polymer materials are used in many electrical products. It is widely believed that space charge plays an important role for the electric field distribution, conduction, ageing, and electric breakdown of polymeric insulation. This paper reviews measurements and characteristics of space charge behavior which mainly determined by the pulsed electro-acoustic (PEA) measurement technique. Particular interests are the effects of the applied voltage, the electrodes, temperature, humidity, microstructure, additives, and filler materials on accumulation, distribution, transport, and the decay of space charge in polymeric materials. This review paper is to provide an overview on various space charge effects under different conditions, and also to summarize the information for polymeric materials with suppressed space charge and improved electrical behavior.
