- α- lwj yog ib qho uas muaj atomic nucleus atomic nucleus Lub nucleus ntawm ib lub atom muaj cov neutrons thiab protons, uas nyob rau hauv lem yog qhov tshwm sim ntawm ntau lub ntsiab lus., hu ua quarks, uas tau tuav hauv kev koom tes los ntawm lub zog nuclear hauv qee qhov kev sib txuas ruaj khov ntawm hadrons, hu ua baryons. https://en.wikipedia.org › wiki › Atomic_nucleus
Atomic nucleus - Wikipedia
emits ib qho alpha particle (helium nucleus) thiab yog li hloov mus rau hauv ib qho txawv atomic nucleus. - Qhov piv txwv n/p yog qhov piv ntawm tus lej ntawm neutrons rau tus naj npawb ntawm protonsuas yog siv rau kev piav qhia ua tiav rau kev kwv yees kev ruaj ntseg ntawm cov nucleus.
Puas n p ratio nce thaum lub sij hawm alpha lwj?
Yog tias qhov N / Z piv ntau dua 1, alpha lwj ua rau nce N / Z piv, thiab yog li muab txoj hauv kev zoo rau kev ruaj ntseg rau kev lwj uas muaj cov nuclei loj nrog ib yam nkaus. ob peb neutron. Positron emissions thiab electron capture kuj nce qhov piv, thaum beta lwj txo qhov ratio.
Yuav ua li cas rau neutron proton piv hauv alpha lwj?
An alpha particle , nrog nws ob protons thiab ob neutrons , yog ib qho heev. ruaj khov configuration ntawm hais. Alpha hluav taws xob txo cov ntawm protons rau neutrons hauv niam txiv nucleus, coj nws mus rau qhov kev teeb tsa ruaj khov dua. Ntau lub nuclei loj dua li txhuasdecay los ntawm txoj kev no.
Yuav ua li cas lwj nce n p ratio?
Tus n / p piv ntawm ib qho atomic nucleus yog qhov piv ntawm nws tus lej ntawm cov neutron rau nws cov naj npawb ntawm protons. Radioactive decay feem ntau tshwm sim los hloov cov n/p piv kom nce stability. Yog tias qhov piv txwv n / p ntau dua 1 (uas yog ib txwm muaj tseeb rau cov xov tooj cua hauv xov tooj cua), alpha lwj nce, qhov n / p ratio.
Yuav ua li cas thaum lub sij hawm alpha lwj?
Alpha lwj yog txheej txheem tawg ntawm nuclear qhov twg ib qho tsis ruaj khov nucleus hloov mus rau lwm lub ntsiab lus los ntawm kev tua tawm ib feem uas muaj ob protons thiab ob neutrons. Qhov ejected particle no hu ua alpha particle thiab tsuas yog helium nucleus. Alpha hais muaj ib qho loj loj thiab muaj tus nqi zoo.
