Spin (ing. spin \u2014 aylanmoq) \u2014 kvant tabiatga ega bo’lgan elementar zar- ralar impulsining xususiy momenti. Elementar zarralarning xususiy magnit momenti S. magnit momenti deb atala- Di. Atom yadrosi (va ba’zan atom) harakat miqdorining xususiy momenti xam S. deb ataladi. «S.»tushunchasini 1925 y.da amerikalik fiziklar J.Ulenbek va S. Proton Gaudsmitlar kiritgan. «S.»ter- Minining qo’llanilishiga sabab, dastlab elektronni o’z o’qi atrofida ailanuvchi zaryadlangan sharcha deb tasavvur kilin- gan. Impulsning xususiy momenti va xususiy magnit momenti ana shu harakat tufayli mavjud, deb hisoblangan. Zarralar S. i shu zarralar bo’ysunadigan statistika bilan bir qiymatli bog’langan. Kvant mexanikada «S.»to’g’risidagi tushunchalar V. Pauli- ga tegishli. Pauli ko’rsatganidek (1940) maydonining kvant nazariyasiga asosan butun sli zarralar Boze \u2014 Eynshteyn statistikasita (bozon- lar), yarimbutun Slilar esa Fermi \u2014 Dirak statistikasiga (fermion- lar) bo’ysunadi. Fermionlar, mas, elek- tronlar uchun Pauli printsipi to’g’ri, bo- zonlar uchun esa o’rinsizdir. Zarralar Si relyativistik effektdir (buni P. Dirak isbotlagan). Elektronda S. va S. magnit momentining mavjudligi Dirak tenglamasidyan kelib chiqadi. Ad.L.Bogolyubov N. N., Shirkov D.
