Txhua qhov kev them nqi nrawm nrawm yuav tso tawm photon. Siv ib qho proton (hydrogen nucleus) thiab txav mus los ntawm kev siv lub tshuab magnetic. Raws li nws hloov cov kev taw qhia thiab / los yog ceev, nws yuav emit ib photon.
Neutrons puas tso tawm photons?
Pab neeg txiav txim siab tias me ntsis ntau dua peb tawm ntawm 1,000 neutron decays ntawm qhov nruab nrab (3.13 ± 0.34 x 10^-3 kom meej), tsim ib photon (ib tug particle ntawm lub teeb) saum toj ib theem zog uas yog tsawg tab sis tseem soj ntsuam.
Puas muaj photons hauv protons?
Cov npe zoo sib xws - photon piv rau proton - tab sis muaj lub ntiaj teb sib txawv. Photons, lossis X-Rays, yog lub zog ntshiab thiab tsis muaj huab hwm coj (txawm tias Einstein yuav tsis pom zoo vim tias lub zog muaj qhov loj). Protons muaj zog thiab kuj loj heev thiab hnyav. Xav txog photons li "fluffy" thiab protons li "portly."
Yuav ua li cas emit photons?
Photons tau tawm hauv ntau cov txheej txheem ntuj. Piv txwv li, thaum tus nqi them ceev nws tawm cov hluav taws xob synchrotron. Thaum lub sij hawm molecular, atomic los yog nuclear hloov mus rau qib qis zog, photons ntawm ntau lub zog yuav raug tso tawm, xws li los ntawm xov tooj cua nthwv dej mus rau gamma rays.
Nucleus puas tuaj yeem tso tawm photon?
fig. 1: Ib tug nucleus emitting ib tug gamma ray . (Analogous rau yuav ua li cas electrons muaj qib zog thiab tso ib photon thaum lawv poob rau hauv lub zog, nuclei kuj muaj zog theem thiab emit photons thaum lawv tsiv los ntawm ib tugzoo siab rau lub xeev tsis muaj zog.
