Rutherford's alpha particle scattering xyaum sim hloov txoj kev peb xav txog atoms. Rutherford qhia cov kab teeb ntawm alpha hais (uas yog lub nuclei ntawm helium atoms thiab li no zoo them) ntawm nyias kub ntawv ci los kuaj cov qauv no thiab sau tseg yuav ua li cas cov alpha hais. tawg tawg los ntawm foil.

Ib yam li ntawd, Rutherford qhov kev sim ua kom tawg tau qhia dab tsi?

Rutherford qhov kev sim tau pom Lub hav zoov ntawm ib tug nuclear atom - ib tug me me, zoo-them nucleus ncig los ntawm qhov chaw khoob thiab tom qab ntawd ib txheej ntawm electrons los tsim sab nraud ntawm lub atom. Feem ntau ntawm alpha hais ua hla ncaj qha los ntawm cov ntawv ci. Lub atom feem ntau yog qhov chaw khoob.

Ib sab saum toj no, Rutherford scattering formula yog dab tsi? Rau ib tug detector ntawm ib lub kaum ntse ntse hais txog qhov teeb meem beam, tus naj npawb ntawm hais ib chav tsev cheeb tsam tawm tsam lub detector yog muab los ntawm lub Rutherford formula : N(θ)=NinLZ2k2e44r2KE2sin4(θ2)

Dab tsi yog qhov kev sim tawg?

Cov kev sim Nws suav nrog firing alpha hais, zoo them helium nuclei ua los ntawm ob protons thiab ob neutrons, ntawm ib txheej nyias ntawm cov ntawv nyiaj kub. Qhov no yog vim hais tias alpha hais yog qhov zoo thiab zoo li cov nqi sib tw, yog li qhov zoo ntawm cov nucleus deflected alpha hais.

Dab tsi yog qhov xaus ntawm Rutherford qhov kev sim ua ntawv kub?

Kev xaus ntawm Rutherford's tawg tawg kev sim : Feem ntau ntawm qhov chaw hauv lub atom yog khoob vim tias feem ntau ntawm α-particles dhau los ntawm ntawv ci tsis tau deflected. Tsawg heev tau deflected los ntawm lawv txoj kev, qhia tau hais tias tus nqi zoo ntawm lub atom occupies tsawg heev qhov chaw.
