<prompt> Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu: Pashure pehondo, Leona Marshall akadzokera kuYunivhesiti yeChicago, kwaakava mushandi paFermis Institute for Nuclear Studies. Achishanda neChicago Pile 3 heavy water reactor, akawana nzira yokuita kuti neutron beams iite 100 muzana spin polarize, uye akaona refractive index ye neutron yezvinhu zvakasiyana-siyana. Mwana wake wechipiri, John Marshall III, akaberekwa muna 1949. Akava purofesa webetsero muna 1953. Mushure mokunge Fermi afa muna 1954, vaMarshall vakaparadzana. John Marshall akadzokera kuLos Alamos Laboratory, nepo Leona, zvino ava amai vasina murume, akava mushandi paInstitute for Advanced Study muPrinceton, New Jersey muna 1957. Gore rakatevera racho akava mushandi paBrookhaven National Laboratory, panguva iyo kutsvakurudza kwomufizikisi kwakanga kuri kuchinja kubva paNucleus uye kuenda kumativi ezvikamu zviduku. Muna 1960, akabatana neNew York University somumwe purofesa wefizikisi. Akava purofesa muna 1962. Makore matatu gare gare, akava purofesa paYunivhesiti yeColorado, achitsvakurudza pamusoro pepamusoro-simba physics, astrophysics uye cosmology. Akabva ava mushandi paRAND Corporation, kwaakashanda kusvika muna 1976. Muna 1966, akarambana naJohn Marshall, uye akaroora Willard Libby, uyo akanga akunda mubayiro weNobel muna 1960. Gare gare akabatana naye kuUCLA, kwaakazova purofesa anoshanyira wezvidzidzo zvezvakatipoteredza, engineering, engineering archaeology, mechanical aerospace uye nuclear engineering muna 1973. Iye zvino anozivikanwa saLeona Marshall Libby, akatanga kufarira nyaya dzezvakatipoteredza uye dzezvakatipoteredza, uye akagadzira nzira yekushandisa isotope ratios yeOxygen-18 kuOxygen-16, Carbon-13 kuCarbon-12, uye Deuterium kuHydrogen mumatanda emiti kuti adzidze shanduko mumamiriro ekunze uye kunaya kwemvura mazana emakore zvisati zvachengetwa zvinyorwa, kuvhura musuwo wekudzidza shanduko yemamiriro ekunze. SaWillard Libby, aive mutsigiri akasimba wekupisa chikafu senzira yekuuraya mabhakitiriya anokuvadza, uye akatsigira kuti mitemo nemitemo inorambidza kushandiswa kwayo isunungurwe. Iye... Mubvunzo: Mwana wechipiri waLeona ainzi ani?  <response>: John Marshall III
