Definition Of Weak Nuclear Force In Physics
Weak nuclear force synonyms weak nuclear force pronunciation weak nuclear force translation english dictionary definition of weak nuclear force.
Definition of weak nuclear force in physics. These nuclei are called radioactive nuclei. Weak interaction also called weak force or weak nuclear force a fundamental force of nature that underlies some forms of radioactivity governs the decay of unstable subatomic particles such as mesons and initiates the nuclear fusion reaction that fuels the sun. The weak force is one of the four fundamental forces that govern all matter in the universe. The weak interaction acts upon left handed fermions i e elementary particles with half integer values of intrinsic angular.
The weak interaction participates in nuclear fission and the theory describing it in terms of both its behaviour and effects is sometimes called. The theory of the weak force was first. When the theory of supersymmetry was developed in 1973 it solved some key problems in particle physics such as unifying three forces of nature electromagnetism the. Three different types of rays or particles are emitted from radioactive nucleus.
These are very heavy particles their mass is about 80 times the proton mass which is why they have such a small range fluctuations where i need to create that much mass are rare. Weak interaction weak force. The weak interaction or weak force is one of the four fundamental forces and involves the exchange of the intermediate vector bosons the w and the z. Define weak nuclear force.
After the theory was introduced it was discovered that there were physical particles that mediate the weak force the w pm and the z 0 bosons. Since these bosons are very massive on the order of 80 gev the uncertainty principle dictates a range of about 10 18 meters which is less than the diameter of a proton. There are some elements found in nature which disintegrate spontaneously for example. Through the process of beta decay it plays a crucial role in powering stars and creating elements.
In nuclear physics and particle physics the weak interaction which is also often called the weak force or weak nuclear force is the mechanism of interaction between subatomic particles that is responsible for the radioactive decay of atoms.
