Positron yog cov tshuaj tiv thaiv rau cov electron. Cov positron muaj tib qhov seem loj (m 0) raws li cov hluav taws xob tab sis cov nqi sib txawv, ib qho zoo hauv cov nqi qis.
Cov piv txwv ntawm cov tshuaj tiv thaiv yog dab tsi?
Feem ntau cov hauv paus ntsiab lus muaj cov khoom sib txuam sib luag, nrog tib lub zog, lub neej, thiab kiv, tab sis nrog cov cim qhia ntawm tus nqi (hluav taws xob, baryonic, lossis leptonic). Lub electron-positron, proton-antiproton, thiab neutron-antineutronyog piv txwv ntawm cov khub no.
Puas yog positron Lub antiparticle ntawm cov electron?
Antiparticle, subatomic particle muaj tib lub zog raws li ib qho ntawm cov khoom ntawm cov teeb meem zoo tib yam tab sis cuam tshuam hluav taws xob thiab lub sijhawm sib nqus. Yog li, positron (positively charged electron) yog cov tshuaj tiv thaiv ntawm cov hluav taws xob tsis zoo.
Vim li cas cov particles muaj antiparticles?
Raws li txoj kev xav quantum teb txhua qhov kev them nqi muaj nws cov tshuaj tiv thaiv, cov khoom nrog tib lub zog thiab tig tab sis rov qab them nqi Qhov txiaj ntsig ntawm quantum teb txoj kev xav tau lees paub los ntawm tag nrho cov ntaub ntawv sim uas twb muaj lawm. Lub antiparticle ntawm lub electron yog lub positron.
Leej twg nrhiav tau antiparticle?
Los ntawm kev kawm cov lem ntawm cosmic rays nyob rau hauv ib tug huab chamber, nyob rau hauv 1932 Carl Anderson nrhiav pom ib tug zoo-them particle nrog ib tug loj seemingly sib npaug zos rau cov electron. Carl Anderson lub particle yog thawj antiparticle pov thawj los ntawm kev sim thiab tau hu ua "positron ".
