Gaseous hydrides
Multielectron photoexcitationsAn absorption cell is constructed for x-ray absorption spectroscopy of reactive, unstable or hazardous gases at
room temperature. In conjunction with in-situ micro-synthesis technique relying on handling the gas in syringes
it enabled a first measurement of x-ray absorption spectra in the region of K and L edges for the series of hydrides
of 5p elements (SnH4, SbH3, TeH2, HI). The signal-to-noise ratio above 103 was achieved, whereby fine detail is
discerned in the spectra, in particular the small sharp features above each absorption edge, testifying of coexcitations
of outer electrons in the core photoeffect.20202020-02-10 12:39:14Delo ni kategorizirano5021COBISS_ID: 5564411DOI: 10.1016/j.radphyschem.2020.108743NUK URN: URN:SI:UNG:REP:MYA2FL65sl
