Chidzidzo ichi chakatsigirwa neyekupihwa kweRussia sainzi yesainzi (rnf) uye yakabudiswa mubhuku remakwikwi emakemikari magazini yeMakemicsynamics magazini. Fiziki yemazuva ano kwemakumi emakore iri kuedza kutsvaga chimiro cheimwe yeiyo yakanyanya kuwanda subatomic zvikamu - neutrino.
Kekutanga, iyo mbichana yakaonekwa pakutanga kwezana ramakumi maviri, apo kana uchiona maitiro ekuora kweBeta (Electron kana positron yakaona kuti huwandu hwesimba risati rasvika uye mushure mekunge vasati vaburitsa, Ndokunge, mutemo wayo wekuchengetedza haubvumirwe. Ipapo iyo Swiss Firchist Wolfgant Pauti akakurudzira kuti kune zvimwe zvidimbu zvidimbu zvinotakura chikamu chesimba navo.
Kuedza, iyi hypothesis yakasimbiswa mushure memakore makumi maviri nematatu. Pakutanga, izvi zvidimbu zvaida kunzi kunzi neutrons, sezvavanoita vasingaenzaniswi nemagetsi, asi izwi iri ratove rakabatikana. Zvidimbu zvakanzi "neutrino" - kubva kuItaria "neutron". Kuwedzera Kudzidza kweNutrino ane masayendisiti emazuva ano anogona kubatsira kunzwisisa chimiro chenyaya, zvimwe zvinhu zvinoputika nyeredzi uye chimiro chechisiko. Vanotsvaga vanotenda kuti muchadenga huwandu hwenyaya hwakakura pamusoro pehuwandu hweantimatter, uye neutrino ichabatsira kutsanangura zvakakonzera izvi kusanzwisisika.

Kune varongi nezve izvo boka rezvikamu zvevhu rinosanganisira neutrinos. Kana isu tichifunga kuti vari muboka reMayorani, ivo, ivo vanonyepedzera ivo, saka masayendisiti ane mukana wekutarisa mutero we beta kuora - kaviri beta-kuora pasina neutrino. Mune ino kesi, nutroni mbiri dzinogona kupfuudza kuora kuora pamwe chete, kuitira kuti neutrino yakabikwa neutron imwe inokwenenzverwa neimwezve neutron. Kuora kwakadaro kusati kuchichengetwa, saka masayendisiti emazuva ano ari kukura mukuvandudzwa kwezviridzwa zvekutsvaga zviitiko zvakadaro.
Mabhodhi anoshandiswa kucherechedza beta kuora (zvishandiso zvekuyera radiation simba) yakagadzirwa neakakwirira-yekuchenera makristori anobvisa mwenje kana uchirova radiation. Chimwe chezvinhu zvekuvimbisa zvekusikwa kwemabhodhi ndeye monocrystals of molomdates yemapoka ekutanga uye echipiri eMendeleev tafura, in the lithium molybdate (li2mooo4).
Mukuwedzera, Alkaline Pasi, molybdates uye tungstat inoshandiswa kudzidza elastic coheriving kupararira neNuclei, iyo inokutendera kuti uwane ruzivo rwezvose zvakasikwa uye kushanduka kwenyeredzi, pamwe nechimiro cheiyo notera uye inogona kushandiswa kutarisa nhetembo yenyukireya. Lithium-yakasimbiswa molybdates ine zvinorema zvinhu (molybdenum uye tungsten), nekuda kwekuti chikamu chemuchinjiko (mukana wekudyidzana) weiyo elastic coherent kupararira kwe neutrino inowedzera.
Masayendisiti eInstitute of Isorganic Chemistry akatumidzwa A. V. Nikolaev mholology yeTungsten Monocrystals Iyo imwechete makristasi akakura uchishandisa nzira yepasi-giredhi yeCzcralsky, kukura kunoitika pakudziya kwakaderera (pasi peimwe degree).
Kubva pane yakawanikwa physicochemical mapatani, vanyori vebasa vakaronga mafambiro umo izvo zvinoshanda zvivakwa zvekristuru zvinoda kuvandudzwa. Semuenzaniso, mukudzidza kwezvidzidzo, zvinongedzo pakati peiyo lattice yerudzi rwezvakanyorwa nemwenje zvakawanikwa, izvo zvinoita kuti zvifanane nekufamba munzira yekuchinja muLuminescent Properties uye kukura nyowani kuvimbisa makristasi asina kuroora. Izvi zvinogona kuitwa nekuwedzera zvimwe zvinhu kune tungsten-molybdate lithium tungsten.
"Uchishandisa makristuru imwe chete, zvichave zvichikwanisika kuita kuyedza nemakirogiramu emakristasi, uye kwete nematani. Sezvakatocherechedzwa, iyo yakapetwa-isina-beta kuora kweguva haisati yacherechedzwa, uye chimiro cheElastic Conent Conent Kupararira kweNeutrino Atomic Atomic Atomic Nokia haina kunyatsonzwisiswa.
Naizvozvo, pamberi pezvinhu zvepasirese zvese, basa racho ndere kuumba zvimwe zvinhu zvakanyanyisa uye nekudzidza zvivakwa zvavo zvinoshanda, "anodaro Nata Matskevich, Chiremba weCemical Science, Projection Manager yeGrant Rnf, Anotungamira Muongorori Laboratori Thermodynamics of Inorganic zvinhu zveInstitute of Inorganic Chemistry Cemistry A.
