Tus qauv no tau sim los ntawm cov kws tshawb fawb Geiger thiab Marsden hauv xyoo 1909. Lawv tau teeb tsa txheej nyias nyias ntawm cov ntawv ci kub thiab tua cov alpha particles - cov xov tooj cua nrogtus nqi zoo - ntawm kub. … Qhov tseeb, cov alpha hais tau deflected ntau tshaj qhov xav tau - ib txhia zoo li thaws yuav luag rov qab.
Kev soj ntsuam kev soj ntsuam ntawm Geiger-Marsden tawg ua kev sim yog dab tsi?
Qhov kev sim Geiger-Marsden (tseem hu ua Rutherford kub foil xyaum ua haujlwm) yog qhov chaw ua yeeb yam ntawm cov kev sim uas cov kws tshawb fawb tau kawm tias txhua lub atom muaj lub nucleus qhov twg tag nrho nws cov nqi zoo thiab feem ntau ntawm nws. pawg yog concentrated.
Qhov kev sim Geiger-Marsden nrhiav tau dab tsi?
Tseem hu ua Geiger-Marsden Experiments, qhov kev tshawb pom tau koom nrog ntau qhov kev sim ua los ntawm Hans Geiger thiab Ernest Marsden hauv qab Ernest Rutherford. Nrog Geiger thiab Marsden qhov kev sim ua pov thawj, Rutherford tau txiav txim siab tus qauv ntawm lub atom, nrhiav pom lub atomic nucleus.
Dab tsi yog qhov tshwm sim ntawm Geiger thiab Marsden alpha tawg kev sim?
Geiger thiab Marsden tau qhia tias tus naj npawb ntawm cov alpha uas tau tawg ua haujlwm raws li kev ua haujlwm ntawm lub kaum sab xis yog zoo ib yam nrog me me, concentrated zoo nucleus. Rau cov ces kaum saum toj no 140 degrees, lub nucleus tshwm sim raws li tus nqi zoo, yog li cov ntaub ntawv no tsis ntsuaslub nuclear loj.
Vim li cas peb thiaj siv cov ntawv nyiaj nyias nyias hauv Geiger-Marsden sim?
Godl ntawv siv hauv Geiger-marsden sim yog li 10^(-8) tuab. Qhov no ua kom. Cov ntaub ntawv tawg tau txheeb xyuas los ntawm kev siv rutherford tus qauv nuclear ntawm lub atom. Raws li cov ntawv kub nyias nyias, nws tuaj yeem xav tias α-particles yuav raug kev txom nyem tsis ntau tshaj li ib qho tawg thaum lawv hla dhau nws.
