20.500.12556/DKUM-59458 High-resolution X-ray absorption spectrometry of atomic vapors A measurement of an x-ray absorption spectrum of a monatomic sample yields pure atomic absorption essential for the EXAFS (Extended X-ray Absorption Fine Structure) analysis in cases of a weak structural signal. A construction of an absorption cell to contain vapor sample takes into account specific properties of the investigated element. Metal-vapor absorption cells for the elements K, Zn, Rb, Cd, Cs, and Hg are presented and comments are made on the use of materials and the operating mechanisms of the cells. Z meritvijo rentgenskega absorpcijskega spektra enoatomnega vzorca dobimo atomsko absorpcijo, ki je nujna za analizo EXAFS (Extended X-ray Absorption Fine Structure - podaljšana drobna struktura rentgenskih absorpcijskih robov), kadar je strukturni signal šibek. Izdelava absorpcijske celice, v kateri hranimo uparjeni vzorec, je odvisna od lastnosti preiskovanega elementa. V prispevku so predstavljene absorpcijske celice za kovinske pare K, Zn, Cd, Rb, Cs in Hg, posebna pozornost pa je namenjena delovanju celic in materialom, ki so bili uporabljeni pri njihovi izdelavi. x-ray absorption atomic vapors K Zn Rb Cd Cs EXAFS x-žarki absorpcija absorpcijske celice K Zn Rb Cd Cs EXAFS true false true Angleški jezik Slovenski jezik Znanstveno delo 2016-05-18 02:56:28 2017-08-18 12:21:08 2022-06-20 03:07:00 2019-07-11 11:14:27 2004 0 0 str. 33-38 št. 1 Letn. 51 2004 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 539.1 14086149 306939 1318-0207 URN:SI:UM:DK:KYPZSZDI Acta_Chimica_Slovenica_2004_Mihelic_et_al._High-resolution_X-ray_absorption_spectrometry_of_atomic_vapors.pdf Acta_Chimica_Slovenica_2004_Mihelic_et_al._High-resolution_X-ray_absorption_spectrometry_of_atomic_vapors.pdf 1 C8BB86C5239E3E50288442389826CF6E 5f453904ff9015774546217bd6f515d1500b6f191ee721f0b9b1ebb05cace352 87bec863-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=115527 http://acta-arhiv.chem-soc.si/51/51-1-33.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=91828 Fakulteta za strojništvo 0 0 0
