Hyperphysics - The Nucleus
Relative scale models of an atom, descriptions of size and density of the nucleus and the strong force, with good links to other sites
A world of particles. Deeper Rutherford
Ernest Rutherford probed inside the atom using alpha particles and found the nucleus. Later, James Chadwick worked out the properties of one of the particles in the nucleus. The next step was to work ...
Hyperphysics - Isotopes
Description of the notation used for different isotopes and the properties of the nucleus with good links to other sites.
Nuclear Physics
This site gives a comprehensive overview of the physics of the nucleus through a series of links to relevant articles.
Gamma-Rays
The term gamma ray is used to denote electromagnetic radiation from the nucleus as a part of a radioactive process.
Max Born
Max Born (1881 - 1970) work, for which he received the Nobel Prize for Physics in 1954 with Walther Bothe, improved the laws describing the movement of electrons around the nucleus in the centre of ...
Structure of Matter
What are atoms made of? What is keeping a nucleus intact? What happens if you try to separate two quarks? Are quarks fundamental? Read the illustrated and animated story about the interior of matter ...
Victor F. Weisskopf
Victor F. Weisskopf (1908 - ) is widely know for his theoretical work in quantum electrodynamics, the structure of the atomic nucleus, and elementary particle physics. He played a critical role in ...
Strong Force
A force which can hold a nucleus together against the enormous forces of repulsion of the protons is strong indeed. However, it is not an inverse square force like the electromagnetic force and it ...
Seyfert Galaxies
The key to classifying a galaxy as a Seyfert Galaxy is the presence of broad emission lines from the bright, star-like nucleus. They are often strong radio and infrared sources. The first such active ...
