Nyob rau hauv alpha lwj ntawm cov xov tooj cua sib txawv, lub zog ntawm alpha hais tau muab piv. Nws tau pom tias thaum lub zog ntawm alpha particle nce ib nrab-lub neej ntawm kev lwj mus zuj zus.
Nyob rau hauv qhov nuclides yog alpha decay feem ntau?
Alpha lwj tshwm sim feem ntau hauv hnyav nuclei (A > 200, Z > 83) Vim tias qhov poob ntawm ib qho α particle ua rau tus ntxhais nuclide nrog cov lej plaub units me dua thiab tus naj npawb atomic ob units me dua cov niam txiv nuclide, tus ntxhais nuclide muaj qhov loj dua n:p.
3 hom xov tooj cua decays yog dab tsi?
Ib yam khoom uas muaj cov nuclei tsis ruaj khov yog suav tias yog xov tooj cua. Peb hom kev lwj ntau tshaj plaws yog alpha lwj (?-decay), beta decay (?-decay), thiab gamma decay (?-decay), txhua yam muaj feem cuam tshuam ib qho. los yog ntau dua.
Cov xwm txheej rau alpha lwj yog dab tsi?
Alpha lwj tshwm sim thaum hnyav atoms saum Z=83 hauv nuclide daim ntawv emit ib qho alpha particle, uas muaj helium nuclei nrog ob neutrons, ob protons, thiab 2. + nqi.
Yuav ua li cas rau cov electrons hauv alpha lwj?
Yog li, thaum alpha particle, uas nqa cov nqi zoo ntawm +2 vim nws qhov tsis muaj electrons, khaws ob lub electrons los ua helium atom, tag nrho cov kab ke. nyob rau hauv uas qhov tshwm sim lwj tshwm sim tseem them nruab nrab.
