Antiparticles yog tsim ib txwm nyob rau hauv qhov chaw thiab ntawm ntau lub hnub lossis hnub qub hauv lub Ntiaj Teb raws li a tshwm sim los ntawm kev sib tsoo ntawm cov khoom siv hluav taws xob siab. High-zog cosmic rays los ntawm qhov chaw tawm tsam atoms nyob rau hauv cov huab cua thiab tsim antiparticles. Lawv sib tsoo sai sai nrog cov khoom teeb meem thiab rhuav tshem.
Vim li cas cov tshuaj tiv thaiv muaj nyob?
Rau txhua qhov tseem ceeb ntawm cov teeb meem, muaj ib qho antiparticle nrog tib lub zog, tab sis tus nqi hluav taws xob rov qab. … Thaum ib tug particle thiab nws cov antiparticle tuaj ua ke, lawv ob leeg ploj mus, heev cia nyob rau hauv ib tug flash, raws li cov txheej txheem kev puas tsuaj hloov lawv cov huab hwm coj mus rau hauv lub zog.
Lub hom phiaj ntawm kev tawm tsam yog dab tsi?
Antimatter yog siv tshuaj . Cov no tau txhaj rau hauv cov hlab ntsha, qhov chaw uas lawv tau tawg lawm, tso cov positrons uas ntsib cov electrons hauv lub cev thiab rhuav tshem.. Cov kev puas tsuaj tsim gamma rays uas yog siv los tsim cov duab.
Vim li cas cov khoom thiab cov tshuaj tiv thaiv tsim?
Particle thiab antiparticle khub yog tsim los ntawm cov khoom loj ntawm lub zog. … Hloov pauv, thaum ib qho khoom ua tau raws li cov tshuaj tiv thaiv, lawv rhuav tshem mus rau hauv lub zog tawg. Thaum lub sij hawm ntawm qhov loj bang, lub siab zog ceev ntawm lub ntug yuav tsum tau tsim ib tug sib npaug npaum li cas ntawm hais thiab antiparticles.
Vim li cas positrons muaj?
Positrons yog tawm hauv qhov zoo beta lwj ntawm proton-nplua nuj (neutron-deficient)radioactive nuclei thiab yog tsim nyob rau hauv khub ntau lawm, nyob rau hauv uas lub zog ntawm ib tug gamma ray nyob rau hauv lub teb ntawm ib tug nucleus yog hloov dua siab tshiab rau hauv ib tug electron-positron khub. … nrhiav pom cov particle hu ua positron.
