High-Resolution Spectroscopy in Fast Atomic Beams
1977
Narrow optical resonances have been observed in fast beams of Na and Cs atoms, obtained from ion beams by charge-transfer collisions with Na, K, or Cs. Corresponding to the narrowing of the velocity distribution, occurring by acceleration, the Doppler width along the beam direction is considerably reduced [1, 2].
Soft X-ray emission spectroscopy used for the characterization of a-C and CNx thin films
2015
Abstract We present the results of a soft X-ray emission spectroscopy study of a-C and CNx films on a Si(100) substrate. Also for the characterization of the homogeneity in depth of these films electron energy loss spectroscopy measurements with localization better than 4 nm were carried out. In case of CNx films the highest diamond-like modification occurs in the region close to the Si(100) substrate. The film density decreases with increasing distance from the substrate and becomes almost constant in range of thicknesses more than ~ 2 nm.
Optical Spectroscopy of Short-Lived Isotopes
1979
This chapter will concentrate on a special branch of the large field of optical spectroscopy, namely, the study of hyperfine structure (hfs) and isotope shift (IS) of short-lived isotopes. Such investigations give information on some basic properties of these nuclei: the spin ( ), the magnetic moment (μI), the spectroscopic quadrupole moment (Q s ), and the change of the mean square charge radius between different isotopes (δ〈r 2〉).
