Shape of the nucleus
WebbA nucleus is composed of a “core” that produces a potential that determines the properties of the “valence” nucleons. These properties determine the behaviour of the nucleus much in the same way that the valance electrons in an atom determine its chemical properties. The excitation levels of nuclei appears to be chaotic and inscrutable. Webb8 maj 2013 · The shape of the nucleus affects how easily it becomes excited in the close encounter. Data from γ-ray detectors showed that radon 220 vibrates between a rough …

In the nucleus, the two protons and two neutrons are depicted in red and blue. This depiction shows the particles as separate, whereas in an actual helium atom, the protons are superimposed in space and most likely found at the very center of the nucleus, and the same is true of the two neutrons.
