In particle physics, Fermi's interaction (also the fermi theory of beta decay) is an explanation of the beta decay, proposed by Enrico Fermi in 1933.〔 〕〔 〕〔 〕〔 〕 The theory posits four fermions directly interacting with one another, at one vertex. For example, this interaction explains beta decay of a neutron by direct coupling of a neutron with: # an electron, # an antineutrino and # a proton.〔 〕 Fermi first introduced this coupling in his description of beta decay in 1933.〔 〕 The Fermi interaction was the precursor to the theory for the weak interaction where the interaction between the proton-neutron and electron-antineutrino is mediated by a virtual W− boson. == History of initial rejection and later publication == Fermi first submitted his "tentative" theory of beta decay to the famous science journal ''Nature'', which rejected it for being "too speculative." ''Nature'' later admitted the rejection to be one of the great editorial blunders in its history. Fermi then submitted the paper to Italian and German publications, which accepted and published it in 1933 in those languages, but it did not appear at the time in a primary publication in English (''Nature'' finally belatedly republished Fermi's report on beta decay in English on January 16, 1939). Fermi found the initial rejection of the paper so troubling that he decided to take some time off from theoretical physics, and do only experimental physics. This would lead shortly to his famous work with activation of nuclei with slow neutrons. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fermi's interaction」の詳細全文を読む スポンサード リンク
