Cov tso pa tawm ntawm gamma rays ua tsis hloov tus naj npawb ntawm protons lossis neutrons nyob rau hauv lub nucleus tab sis es tsis txhob muaj cov nyhuv ntawm kev txav lub nucleus los ntawm qhov siab dua mus rau lub xeev qis zog (tsis ruaj khov). Gamma ray tso pa tawm nquag ua raws beta lwj , alpha lwj , thiab lwm yam nuclear lwj txheej txheem.

Ua raws li qhov xav tau, puas yog alpha lwj ib txwm helium?

Hauv alpha lwj , zog thiab ib alpha particle yog emitted los ntawm ib tug nucleus uas tsis ruaj tsis khov vim nws muaj ntau protons. Ib alpha particle Nws muaj ob lub protons thiab ob lub neutrons, yog li nws yog qhov tseeb helium nucleus. Tag nrho radioactive lwj yog txaus ntshai rau tej yam muaj sia, tab sis alpha lwj yog qhov txaus ntshai tshaj plaws.

Qhov thib ob, yuav ua li cas rau alpha hais tom qab lwj? Alpha lwj los yog α- lwj yog hom xov tooj cua lwj nyob rau hauv uas lub atomic nucleus emits ib alpha particle (helium nucleus) thiab yog li hloov los yog ' lwj ' rau hauv ib qho txawv atomic nucleus, nrog ib tug loj tus naj npawb uas yog txo los ntawm plaub thiab ib tug atomic tooj uas yog txo los ntawm ob.

Yog li ntawd, alpha beta thiab gamma lwj yog dab tsi?

Alpha lwj yog qhov feem ntau hauv cov ntsiab lus nrog tus lej atomic ntau dua 83. Beta lwj yog feem ntau nyob rau hauv cov ntsiab lus nrog siab neutron rau proton piv. Gamma lwj ua raws li daim ntawv: In gamma emission, tsis yog tus lej atomic lossis tus lej loj hloov pauv.

Yuav ua li cas gamma lwj tshwm sim?

Gamma lwj , nyob rau hauv sib piv, tshwm sim thaum lub nucleus nyob rau hauv ib qho kev zoo siab thiab muaj zog ntau dhau los ua kom ruaj khov. Qhov no feem ntau tshwm sim tom qab alpha lossis beta lwj tau tshwm sim. Vim tias tsuas yog lub zog tawm thaum lub sijhawm gamma lwj , tus naj npawb ntawm protons tseem zoo li qub.
