Giant Resonances

Abstract

Aust. J. Phys., 1976, 29, 511-59 A review is given of giant muitipole resonances in nuclei with emphasis on their systematic location, their great strength in terms of an appropriate sum rule and their concentration in a rather narrow region. Capture reactions as a source of information are especially considered.

Stability of Nuclei Based on the New Proton and Neutron Model

“…To overcome the repulsive effect of positively charged protons located on the surface of the nucleus, which are weakly bound to the nucleus, the electron density increases, creating a layer of nearly-neutral nucleons, or neutrons, called neutron skin. Experiments have shown that the density of the nucleus is higher than the band forming the surface of the nucleus, which is neutrally charged [30][31][32][33][34][35][36]. Thus, the nucleus is bounded by neutrally charged nucleons, that is, the nucleus is surrounded by so-called neutron skin.…”
