http://en.wikipedia.org/wiki/Gamma_spectroscopy The gamma-ray spectrum of natural uranium , showing about a dozen discrete lines superimposed on a smooth continuum, allows the identification the nuclides 226 Ra , 214 Pb , and 214 Bi of the uranium decay chain . Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources , in the nuclear laboratory and nuclear process, and in geochemical, astrophysical and other radiation measurement contexts. Most radioactive sources produce gamma rays of various energies and intensities.

Introduction This page summarises summarises the classic Stern-Gerlach experiment on "spin" and extends the treatment to a discussion of correlation experiments.

The search for the Higgs Boson was one of the main reasons for building the Large Hadron Collider. Finding the Higgs Boson would give an incredible leap to our understanding of how the universe was created, helping us answer the fundamental questions of how and why stars, planets and people came to exist at all. The Higgs Boson is proving difficult to detect because it isn’t visible long enough to be photographed. Scientists can’t catch one, but they can look for evidence that one has been in the detector. Like an exploding firework, it leaves a particular display, with different particles behaving a bit like different kinds of firework. What makes the job of analyzing them so complicated, is that billions of these fireworks are going off every second, and many of them look very similar!
