weak interaction [′wēk ‚in·tər′ak·shən] (particle physics) One of the fundamental interactions among elementary particles, responsible for beta decay of nuclei, and for the decay of elementary particles with lifetimes greater than about 10-10second, such as muons,Kmesons, and lambda hyperons; it is several orders of magnitude weaker than the strong and electromagnetic interactions, and fails to conserve strangeness or parity. Also known as beta interaction. How to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit webmaster's page for free fun content. |

| Therefore, the size of the PV spin rotation is a direct measure of the strength of the weak nuclear interaction. Those disturbing fragments of data prompted an intensive, four-year quest for evidence of a new force of nature to join the four types already known: gravity, electromagnetism, and the strong and weak nuclear interactions. Electrons in atoms "feel" not only the electromagnetic force between an electron and a positively charged nucleus, but also the much smaller influence due to the weak nuclear interaction. |
