Positrons yog cov tshuaj tiv thaiv, uas yog, raug nqi beta-rays Muaj cov nqi zoo, lawv raug nyiam rau cov hluav taws xob tsis zoo tab sis rov qab los ntawm atomic nuclei atomic nuclei Lub nucleus ntawm atom muaj cov neutrons thiab protons, uas nyob rau hauv lem yog qhov tshwm sim ntawm ntau lub hauv paus ntsiab lus, hu ua quarks, uas yog tuav nyob rau hauv lub koom haum los ntawm nuclear zog quab yuam nyob rau hauv tej yam ruaj khov ua ke ntawm hadrons, hu ua baryons. https://en.wikipedia.org › wiki › Atomic_nucleus

. Lawv raug rhuav tshem nrog ib qho hluav taws xob, nrog rau qhov seem ntawm ob qhov khoom tshwm sim li gamma-ray emission.
Puas positrons zoo them?
Positron, tseem hu ua qhov zoo electron, raug them zoosubatomic particle muaj tib qhov loj thiab qhov loj ntawm tus nqi raws li cov hluav taws xob thiab tsim cov tshuaj tiv thaiv ntawm cov hluav taws xob tsis zoo.
Puas positrons muaj lub zog tsis zoo?
Piv txwv li, nws yeej tsis muaj tseeb tias a positron muaj lub zog tsis zoo kinetic … Txoj cai cais tawm ib txwm tiv thaiv lub zog zoo hluav taws xob los ntawm kev hloov mus rau cov xeev tsis zoo. Txawm li cas los xij, nws tseem muaj peev xwm ua rau cov hluav taws xob zoo li no poob rau hauv lub xeev tsis muaj zog ntawm lub zog tsis zoo.
Puas yog positron ib qho hluav taws xob?
Yog li ntawd, ib qho positron tuaj yeem yog suav tias yog ib qho hluav taws xob uas muaj hluav taws xob zoo. Thaum twg ib qho electron thiab positron los ze, lawv rhuav tshem ib leeg thiab tsim lub zog hauv daim ntawv ntawm photons.
Puas yog positrons protons?
Qhov Sib Txawv Tseem Ceeb – Proton vs Positron
Ib tug proton yog ib qho subatomic particle uas muaj hluav taws xob zoo (+1). A positron kuj yog ib qho txiaj ntsig zoo subatomic particle Qhov sib txawv tseem ceeb ntawm proton thiab positron yog qhov loj ntawm ib qho proton yog qhov siab dua li ntawm positron.
