Nuclear masses and the equation of state of nuclear matter
Kazuhiro Oyamatsu
The incompressible liquid-drop (ILD) model reproduces masses of stable nuclei rather well. Here we show how the ILD volume, surface, symmetry, and Coulomb energies are related to t…
Energy and mass-number dependence of hadron-nucleus total reaction cross sections
Akihisa Kohama, Kei Iida, Kazuhiro Oyamatsu
We systematically analyze nuclear reaction data that are sensitive to nuclear size, namely, proton-nucleus total reaction cross sections and differential elastic cross sections, us…
Symmetry energy, unstable nuclei, and neutron star crusts
Kei Iida, Kazuhiro Oyamatsu
Phenomenological approach to inhomogeneous nuclear matter is useful to describe fundamental properties of atomic nuclei and neutron star crusts in terms of the equation of state of…
Proton-nucleus total reaction cross sections in the optical limit Glauber theory: Subtle dependence on the equation of state of nuclear matter
K. Iida, K. Oyamatsu, B. Abu-Ibrahim +1
We calculate the proton-nucleus total reaction cross sections at different energies of incident protons within the optical limit approximation of the Glauber theory. The isospin ef…
Proton inelastic diffraction by a black nucleus and the size of excited nuclei
Kei Iida, Shinya Koide, Akihisa Kohama +1
We systematically derive a length scale characterizing the size of a low-lying, beta stable nucleus from empirical data for the diffraction peak angle in the proton inelastic diffe…
Curvature effect on nuclear pasta: Is it helpful for gyroid appearance?
Ken'ichiro Nakazato, Kei Iida, Kazuhiro Oyamatsu
In supernova cores and neutron star crusts, nuclei are thought to deform to rodlike and slablike shapes, which are often called nuclear pasta. We study the equilibrium properties o…
