WebThe atomic nucleus is composed of protons and neutrons ( Figure 10.2 ). Protons and neutrons have approximately the same mass, but protons carry one unit of positive charge ( + e), and neutrons carry no charge. These particles are packed together into an extremely small space at the center of an atom. http://www-naweb.iaea.org/napc/ih/documents/global_cycle/vol%20I/cht_i_02.pdf

Web11 apr. 2024 · Atomic spectroscopy is used to search for the space-time variation of fundamental constants which may be due to an interaction with scalar and pseudo-scalar (axion) dark matter. In this letter, we study the effects which are produced by the variation of the nuclear radius and electric quadrupole moment. The sensitivity of the electric …
Although the standard model of physics is widely believed to completely describe the composition and behavior of the nucleus, generating predictions from theory is much more difficult than for most other areas of particle physics.
