Kuidas näha väga kiireid laetud osakesi?
Kui laetud osake, näiteks elektron, liigub läbi dielektriku kiirusega, mis on suurem valguse kiirusest selles keskkonnas, siis tekib kiirgus, mida nimetatakse selle avastaja järgi Cherenkovi kiirguseks. Näiteks vees paiknevate tuumareaktorite kiiratav sinine valgus on justnimelt Cherenkovi kiirgus ja selle järgi on võimalik beeta-kiirguse olemasolu kindlaks teha (vt pilti). Sellist, kiirete laetud osakeste poolt tekitatud kiirgust […]

Mida see peaks tähendama? Mitteosakestefüüsikute keeles tähendab see tõenäosust umbes 1/1000000, et tegu ei ole uue osakesega. Osakestefüüsikud on kokku leppinud, et sellist olukorda nimetatakse osakese avastuseks.” Mis on see salapärane […]
