Webb5 mars 2024 · Nuclei act like superfluids, so their moment of inertia is much smaller than the rigid-body value. Most nuclei are either spheres or prolate ellipsoids, or unstable shapes that vibrate back and forth between such shapes. There are basically no known cases of stably oblate nuclei. 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.

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. Webb2 juli 2024 · The overall shape of a nucleus is mostly spherical, but nuclei which are very large or have a lot of angular momentum may deviate from the sphere. A nucleus with nonzero “quadrupole moment” may be “prolate” (elongated like a cigar or an American football) or “oblate” (flattened like a coin).
