Exciting Possibilities of Soft X-ray Emission Spectroscopy as Chemical State Analysis in EPMA and FESEM

A novel wavelength dispersive soft X-ray emission spectrometer (WD-SXES) has been developed. It covers nominally the X-ray energy range between 50 and 210 eV [1, 2]. One of the characteristic features of the WD-SXES is parallel detection of the signal so that it can be used like a conventional energy dispersive spectrometer. One other feature is a high energy resolution, which is about 0.2 eV. ...

Chemical analysis of impurity boron atoms in diamond using soft X-ray emission spectroscopy.

To analyze the local structure and/or chemical states of boron atoms in boron-doped diamond, which can be synthesized by the microwave plasma-assisted chemical vapor deposition method (CVD-B-diamond) and the temperature gradient method at high pressure and high temperature (HPT-B-diamond), we measured the soft X-ray emission spectra in the CK and BK regions of B-diamonds using synchrotron radia...

Electronic structure and chemical bonding in Ti2AlC investigated by soft x-ray emission spectroscopy

Quantum Chemical Calculations of X-ray Emission Spectroscopy.

The calculation of X-ray emission spectroscopy with equation of motion coupled cluster theory (EOM-CCSD), time-dependent density functional theory (TDDFT), and resolution of the identity single excitation configuration interaction with second-order perturbation theory (RI-CIS(D)) is studied. These methods can be applied to calculate X-ray emission transitions by using a reference determinant wi...

Ultra-soft X-ray Emission Spectroscopy a Progress Report

A review is presented on recent developments in ultra-soft x-ray emission spectroscopy. Especially, instrumental developments related to high resolution studies of free molecules and to the use of synchrotron radiation are discussed. The most recent results from three different applications of ultra-soft x-ray emission spectroscopy are presented: electron excited spectra of free molecules, mono...
