Alpha vs Beta Particles
Alpha hais thiab beta hais yog ob hom hluav taws xob hluav taws xob uas tau tham dav dav hauv thaj chaw xws li nuclear physics, atomic zog, cosmology, astrophysics, astronomy thiab ntau yam haujlwm. Nws yog ib qho tseem ceeb kom muaj kev paub zoo hauv cov ntsiab lus tom qab alpha hais thiab beta hais kom ua tau zoo hauv cov haujlwm no. Alpha hais muaj tib lub ntsiab lus ntawm lub nucleus ntawm helium atom. Beta hais yog positrons lossis electrons. Ob hom particle no tseem ceeb heev nyob rau hauv cov teb no. Hauv tsab xov xwm no, peb yuav tham txog dab tsi alpha hais thiab beta hais yog, lawv cov ntsiab lus, yuav ua li cas alpha particles thiab beta hais raug tsim, kev siv ntawm alpha hais thiab beta hais, lawv qhov sib xws, thiab thaum kawg qhov sib txawv ntawm alpha particle thiab beta particle..
Alpha Particle
Alpha hais yog npe tom qab thawj tsab ntawv hauv Greek cov tsiaj ntawv tus ntawv α. Alpha hais kuj txhais tau tias yog α - hais. Alpha hais yog classically tsim nyob rau hauv alpha lwj, tab sis lawv tuaj yeem tsim los ntawm ntau yam kev tawm tsam nuclear, thiab. Alpha lwj tshwm sim hauv atoms nrog hnyav nuclei. Nrog alpha lwj, thawj lub caij dhau los ua ib qho sib txawv nrog tus lej atomic ob tsawg dua qhov pib atom. Ib qho alpha particle muaj ob lub neutrons thiab ob protons khi ua ke. Cov qauv no zoo ib yam li cov nucleus ntawm helium atom. Yog li, alpha hais kuj tuaj yeem txhais tau tias yog He 2 +Net spin ntawm ib qho alpha particle yog xoom. Tag nrho cov hluav taws xob nuclear muaj cov cuab yeej hu ua lub zog nkag mus, uas piav qhia tias qhov tob npaum li cas tuaj yeem nkag mus rau hauv cov khoom siv. Alpha hais muaj lub zog nkag mus tsawg heev. Qhov no txhais tau hais tias ib phab ntsa nyias yog txaus rau nres alpha hais. Tab sis lub zog siab alpha hais xws li cosmic rays muaj lub zog nkag siab heev. Alpha hais tuaj yeem tawg mus rau ntau qhov tseem ceeb subatomic hais nrog lub zog sib tsoo.
Beta Particle
Beta hais muaj npe tom qab tsab ntawv thib ob hauv Greek cov tsiaj ntawv tus ntawv β. Beta particles kuj txhais tau tias yog β-particles. Beta hais yog lub zog hluav taws xob siab lossis siab zog positrons. Cov no yog emissions nyob rau hauv lwj ntawm ntau yam radioactive nuclei xws li Potassium - 40. Muaj ob hom beta lwj. Thawj qhov yog β– - lwj, uas tseem hu ua electron lwj. Hom thib ob yog β+ - lwj, uas tseem hu ua positron lwj. Nyob rau hauv electron lwj, ib tug neutron converts mus rau hauv ib tug proton, ib tug electron, thiab ib tug antineutrino. Nyob rau hauv positron lwj, ib tug neutron converts mus rau hauv ib tug proton, ib tug positron thiab ib tug neutrino.
Qhov txawv ntawm Alpha Particle thiab Beta Particle yog dab tsi?
• Alpha hais muaj ob peb nucleons whereas beta particle tsuas muaj ib nucleon xwb.
• Alpha particles muaj lub zog nkag mus rau qhov qis thaum beta hais muaj lub zog nkag mus nruab nrab.
• Tsuas muaj ib hom alpha hais xwb, tab sis muaj ob hom beta particles.
• Alpha particles hnyav heev txheeb ze rau beta hais (kwv yees li 6500 npaug hnyav dua).
