Kev kwv yees Yug-Oppenheimer yog qhov kev xav tias cov hluav taws xob hluav taws xob thiab cov lus tsa suab nuclear hauv cov molecules tuaj yeem sib cais. … Tus Yug-Oppenheimer (npe rau nws cov thawj inventors, Max Born thiab Robert Oppenheimer) yog raws li qhov tseeb hais tias nuclei muaj ob peb txhiab zaus hnyav dua electrons.
Lub hauv paus ntawm Born-Oppenheimer kwv yees yog dab tsi?
Qhov kwv yees Yug-Oppenheimer tsis quav ntsej qhov kev txav ntawm lub atomic nuclei thaum piav txog cov hluav taws xob hauv cov molecule. Lub hauv paus ntawm lub cev rau Born-Oppenheimer kwv yees yog qhov tseeb tias qhov loj ntawm lub atomic nucleus nyob rau hauv ib lub molecule loj dua li qhov loj ntawm ib qho hluav taws xob (ntau tshaj 1000 zaug).
Vim li cas peb thiaj siv Born-Oppenheimer approximation?
Hauv kev suav molecular physics thiab lub xeev physics lub Born-Oppenheimer kwv yees yog siv los cais cov quantum mechanical motion ntawm cov electrons los ntawm kev txav ntawm nuclei. Txoj kev cia siab rau qhov loj loj piv ntawm electrons thiab nuclei.
Qhov kwv yees Yug-Oppenheimer tso cai rau peb xaus li cas?
Kev kwv yees Yug-Oppenheimer yog ib qho ntawm cov ntsiab lus tseem ceeb hauv qab cov lus piav qhia ntawm quantum xeev ntawm molecules. Qhov kev kwv yees no ua rau nws muaj peev xwm cais qhov kev txav ntawm lub nuclei thiab kev txav ntawm cov electrons.
Dab tsi yog qhov tseem ceeb ntawm Born-Oppenheimer kwv yees thiab thaum twg qhov kev kwv yees no tawgnqes?
Peb rov hais dua tias thaum ob lossis ntau lub zog muaj peev xwm ntog ib leeg, lossis tseem hla, qhov kwv yees Yug-Oppenheimer tawg, thiab ib qho yuav tsum poob rov qab rau ntawm qhov sib npaug sib npaug..

Vim li cas groves thiaj txiav txim siab ntiav oppenheimer?
Ua kom nws txoj haujlwm nyuaj yog cov phiaj xwm ntxov los ua haujlwm Los Alamos ua tub rog kuaj. Oppenheimer tau lees txais Groves qhov laj thawj rau qhov kev npaj no tab sis tsis ntev tau pom tias cov kws tshawb fawb tau tawm tsam kev ua haujlwm raws li cov tub ceev xwm thiab ntshai tias cov tub rog ntawm cov lus txib tsis haum rau kev txiav txim siab.
Oppenheimer puas tuaj yeem ntseeg tau?
Edward Teller Edward Teller Edward Teller (1908-2003) yog ib tug neeg Hungarian-yug American theoretical physicist. Nws yog suav tias yog ib tus txiv ntawm lub foob pob hydrogen. Teller, nrog rau Leo Szilard thiab Eugene Wigner, tau pab yaum Thawj Tswj Hwm Roosevelt los tsim ib txoj haujlwm foob pob atomic hauv Tebchaws Meskas.
Puas yog oppenheimer khuv xim lub foob pob atomic?
Openheimer ntseeg tias nws muaj ntshav ntawm nws txhais tes rau nws lub luag haujlwm hauv kev tsim lub foob pob atomic. … Thaum nws tawm tsam H-pob zeb thiab tu siab rau nws lub luag haujlwm yog "txiv ntawm lub foob pob atomic", Oppenheimer tus kheej kev coj ncaj ncees yog qhov nyuaj heev thiab tsis hais los ntawm ib qho kev ntseeg lossis kab lis kev cai.
