Thaum lub sijhawm beta-muas rho tawm, ib lub neutron hauv atom lub nucleus hloov mus ua ib qho proton, electron thiab antineutrino. … Txawm hais tias tus lej ntawm protons thiab neutrons nyob rau hauv ib qho atom lub nucleus hloov thaum lub sij hawm beta lwj, tag nrho cov hais (protons + neutrons) tseem zoo ib yam.
Yuav ua li cas thaum lub sijhawm beta rho tawm?
Beta lwj tshwm sim thaum, nyob rau hauv lub nucleus uas muaj ntau protons los yog ntau neutrons, ib tug ntawm cov protons los yog neutrons hloov mus rau lwm yam. … Nyob rau hauv beta minus decay, a neutron decays rau hauv ib tug proton, ib tug electron, thiab antineutrino: n Æ p + e - +.
beta rho tawm puas cuam tshuam rau tus lej atomic li cas?
Raws li qhov tshwm sim ntawm beta decays, qhov loj ntawm cov atoms tseem zoo li qub, tab sis tus lej atomic hloov: atomic tooj nce hauv qhov tsis zoo beta lwj thiab txo qis hauv qhov zoo beta lwj, feem.
Dab tsi tso tawm thaum lub sijhawm beta lwj?
Atoms emit beta hais los ntawm cov txheej txheem hu ua beta lwj. Ib hom (zoo beta decay) tso ib tug zoo them beta particle hu ua ib tug positron, thiab ib tug neutrino; lwm hom (tsis zoo beta decay) tso tawm qhov tsis zoo them beta particle hu ua electron, thiab antineutrino. …
Yuav ua li cas rau quarks hauv beta rho tawm?
Nyob rau hauv beta ntxiv rau lwj qhov nce quark hloov mus rau hauv qis quark nrog lub emission ntawm positron thiab ib tug neutrino, thaum nyob rau hauv beta minus decay a down quarkHloov mus rau hauv ib qho quark nrog cov emission ntawm electron thiab anti-neutrino. Lub quarks tau tuav ua ke hauv lub nucleus los ntawm lub zog muaj zog nuclear.
