Gamma tawg yog qhov tshwm sim ntawm gamma ray. Nyob rau hauv qhov tseeb, lub nucleus emits ib tug high-energ proton. Qhov no yog qhov tob heev thiab tuaj yeem nres ntawm txhuas, txhuas, av, dej, thiab pob zeb. Hom hluav taws xob no tsis hloov lub caij thiab, yog li, tsis ua rau muaj kev hloov pauv.
Dab tsi lwj ua rau hloov pauv?
Kev hloov pauv, hloov pauv ntawm ib qho tshuaj mus rau lwm qhov. Ib qho kev hloov pauv hloov pauv hauv cov qauv ntawm atomic nuclei thiab vim li no tej zaum yuav raug ntxias los ntawm cov tshuaj tiv thaiv nuclear (q.v.), xws li neutron capture, los yog tshwm sim spontaneously los ntawm radioactive decay,xws li alpha decay thiab beta decay(qq.
Puas yog radioactive decay a transmutation?
Raws li lub atom tsis ruaj khov sim mus cuag ib daim ntawv ruaj khov, lub zog thiab cov teeb meem raug tso tawm los ntawm lub hauv paus. Qhov kev hloov pauv ntawm cov nucleus no yog hu ua radioactive decay. Thaum muaj kev hloov pauv hauv lub hauv paus thiab ib lub ntsiab hloov mus rau lwm qhov, nws yog hu ua transmutation.
Gamma lwj cuam tshuam dab tsi?
Nyob rau hauv gamma decay, depicted nyob rau hauv daim duab 3-6, ib tug nucleus hloov ntawm lub zog siab dua mus rau lub zog qis zog los ntawm emission ntawm electromagnetic hluav taws xob (photons). Tus naj npawb ntawm cov protons (thiab neutrons) nyob rau hauv lub nucleus tsis hloov hauv cov txheej txheem no, yog li niam txiv thiab tus ntxhais atoms yog tib yam tshuaj lom neeg.
Puas beta lwj yog piv txwv ntawm kev hloov pauv?
ibhom kev hloov pauv ntawm ntuj pom nyob rau tam sim no tshwm sim thaum qee yam xov tooj cua muaj nyob hauv cov xwm txheej spontaneously lwj los ntawm cov txheej txheem uas ua rau hloov pauv, xws li alpha lossis beta lwj. Ib qho piv txwv yog lub ntuj lwj ntawm potassium-40 rau argon-40, uas ua rau feem ntau ntawm argon nyob rau hauv huab cua.
