WebBeta Decay: Fermi’s Theory According to Enrico Fermi’s proposed theory, the 4 fermions interact directly with one another at one vertex. This type of interaction takes place by coupling an electron with a neutron, a neutrino and also a proton. This theory was formulated by Fermi in 1933. Things to Remember: http://oldsite.pup.ac.in/e-content/science/physics/MScPhy79.pdf Webplot indicates that Fermi’s theory of beta decay is correct.

WebFeb 2, 2014 · The history of weak interactions starting with Fermi’s creation of the beta decay theory and culminating in its modern avatar in the form of the electroweak gauge theory is described. Discoveries of parity violation, matter-antimatter asymmetry, W and Z bosons and neutrino mass are highlighted. Download to read the full article text. Webn0 → p+ + e− + νe James Chadwick discovered a much more massive nuclear particle in 1932 and also named it a neutron, leaving two kinds of particles with the same name. Enrico Fermi, who developed the theory of beta decay, coined the term neutrino (the Italian equivalent of "little neutral one") in 1933 as a way to resolve the confusion.

Radioactivity was discovered in 1896 by Henri Becquerel in uranium, and subsequently observed by Marie and Pierre Curie in thorium and in the new elements polonium and radium. In 1899, Ernest Rutherford separated radioactive emissions into two types: alpha and beta (now beta minus), based on penetration of objects and ability to cause ionization. Alpha rays could be stopped by thin sheets of paper or aluminium, whereas beta rays could penetrate several millimetres of alu… WebApr 22, 2008 · In that limit, the IVB calculation becomes identical to the four-Fermi calculation (at the condition of using the appropriate four-Fermi coupling). So the two apporaches give the same result at low energies. At high energies, however, the results for the cross sections are completely different.
