The Octahedron in Magnesium The story of SS-8: how a formula written for the strict-N=Z alpha-chain turned out to hide a deeper combinatorial structure, how a Platonic solid two-and-a-half thousand years old appeared inside a magnesium nucleus, and how the same...

An Alpha Pattern Discovery

Eight Nuclei in a Row The story of SS-7: how a formula written for the smallest atomic nuclei turned out, almost by accident, to predict the weights of nuclei a hundred times larger — and how the first thing that seemed wrong about the result, when it was finally...

Nuclear Spin-Orbit Coupling

Strong Spin–Orbit Coupling in Nuclear Physics In nuclear physics, strong spin–orbit coupling is the crucial interaction that makes the nuclear shell model work and explains the observed magic numbers. Below is a clear, step-by-step explanation of what it is, why it is...

Nuclear Magic Numbers

Magic Numbers in Nuclear Physics Magic numbers are one of the key organizing principles in nuclear physics. They explain why certain nuclei are exceptionally stable, much like noble gases in atomic chemistry. What Are Magic Numbers? In nuclear physics, a magic number...
