Spin, s, yog kev sib hloov ntawm ib qho ntawm nws axis, raws li lub ntiaj teb tig ntawm nws axis. Lub kiv ntawm ib qho particle tseem hu ua intrinsic angular momentum. Tag nrho cov angular momentum ntawm ib tug particle yog lub spin ua ke nrog lub angular momentum los ntawm cov khoom txav. …
Puas subatomic particles tiag spin?
Tsis ntev cov lus 'spin' tau siv los piav txog qhov pom meej ntawm kev sib hloov ntawm subatomic hais. Spin yog qhov txawv txav ntawm lub cev. Nws yog qhov zoo sib xws rauspinntawm lub ntiaj teb nyob rau hauv uas nws muab ib qho me me angular momentum thiab me me magnetic teb hu ua lub sij hawm sib nqus.
Pob atoms muaj kiv?
Cov khoom me me muaj cov cuab yeej hu ua "kiv" uas tuaj yeem xav tias yog tig ncig lawv axes. … Ib yam li cov hluav taws xob, cov atoms hauv cov roj yog fermions, cov khoom uas tsis tuaj yeem sib koom tib lub xeev quantum; Raws li qhov tshwm sim, txhua lub atom yuav tsum muaj qhov sib txawv ntawm qhov sib txawv ntawm kev sib tw thiab nrawm.
Atomic particle spin yog dab tsi?
Spin, hauv physics, tus nqi ntawm lub zog angular cuam tshuam nrog subatomic particle lossis nucleusthiab ntsuas hauv ntau chav tsev hu ua Dirac h, lossis h-bar (ℏ), sib npaug ntawm Planck tas li muab faib los ntawm 2π. Rau electrons, neutrons, thiab protons, qhov ntau yog 0.5; pions muaj pes tsawg spin.
Electrons tig li cas?
Electron spin yog quantum khoom ntawm electrons. Nws yog ib daim ntawv ntawm angular momentum.… Raws li ib txoj kev qhia, cov kws qhia qee zaus piv cov tshuab hluav taws xob rau lub ntiaj teb uas tig ntawm nws tus kheej txhua 24 teev. Yog hais tias lub electron tig clockwise ntawm nws axis, nws yog piav raws li spin-up; counterclockwise yog tig-down.
