In this chapter, experimental and theoretical investigations of the matter radii and density distributions, mainly concerning developments in the last two decades, are described. For stable nuclei, investigations of the neutron density radii are still developing. Measurements of the neutron skin thickness...

Key words In this work, the calculation of matter density distributions, elastic charge form factors and size radii for halo 11 Be, 19 C and 11 Li nuclei are calculated. Each nuclide under study are divided into two parts; one for core part and the second for halo part. The core part ...
Different ground-state properties, binding energies, rms radii, density distributions, are then systematically analyzed and discussed. A remarkable agreement with experimental quantities is found and further possibilities are suggested.doi:10.1016/0375-9474(84)90364-6A. Bouyssy...
Nuclear-Reaction Cross-Sections at High Energies and Radii of Radioactive Nuclei. Radius of the 6He Nucleus The cross-section of the radioactive 6He nucleus interaction with 9Be, 12C and 27Al nuclei is calculated at the 6He energies of 790 MeV/nucleon with the 6He density parametrization fr...
In Fig.3, we next show a detailed investigation of the posterior distributions of the quantities displayed in Fig.2. The results are shown both as two-dimensional CIs for the joint distributions between pairs of quantities and as one-dimensional probability density functions, all displayed for bot...
A Family of Potential-Density Pairs for Spherical Galaxies and Bulges A family of spherical potential鈥揹ensity pairs is presented. The densities are proportional to at large radii and diverge in the centre as with . The mode... D Walter - 《Monthly Notices of the Royal Astronomical Society...
Too Big to Fail (TBTF) problem: The discrepancy between the measured densities at the half-light radii of the brightest local dwarf galaxies and the (higher) densities of the most-massive subhalos in ΛCDM simulations, i.e. an over-abundance in simulations of massive substructures that are ex...
They demonstrated that within the analytical framework of their model, a single axion mass cannot simultaneously explain the observed wide range of DM core radii (rs) and reproduce the observed core-scaling relation ρs≈rs−1 [24,25,26]. However, this interesting result does not take into ...
The constraints are strongest above 1.5nsat, for which the extrapolation in the speed of sound is used for the EOSs. The high-density astrophysical constraints affect mostly the high-mass region in the mass–radius plane and exclude the stiffest EOSs that lead to the largest radii (Fig.2b)....
