Orientation of 1s electrons using tilted foils
نویسنده
چکیده
The prospects for producing orientation of the 1s level in highly charged ions using tilted foils is discussed. We analyse the transfer of orientation from the initial orbital angular momentum of an ion emerging from a foil to the ground-state spin via a combination of the spin–orbit interaction and cascade decays. An enhancement of the orientation can be obtained using a multi-tilted-foil technique similar to that used to orient nuclei.

TRAX simulations
One of the design points of TRAX current developments is the ability to reproduce experimental results obtained by GSI’s Toroid low-energy (< 1 keV) electron spectrometer [2]. The main idea is to verify experimentally the model assumptions about electron creation and transport in thin foils bombarded with ions or electrons. In its latest version TRAX has been extended to formally handle (via ex...
متن کاملOptical properties of a semi-infinite medium consist of graphene based hyperbolic meta-materials with tilted optical axis
In this paper, the optical properties of a semi-infinite medium composed of graphen-based hyperbolic meta-materials with the optical axis were tilted with respect to its boundary with air, by using the Maxwell equations; then the homogeneous effective medium approximation method was studied. The results showed that the orientation of the structure layers (geometric induced anisotropy) affec...

The secondary electron emission coefficient from several elements in the form of thin foils has been measured using 70 MeV electrons as bombarding particles. Using foils with different atomic numbers, it was found that the secondary emission coefficient per target electron in the metal is noticeably larger for light elements, especially in cases of beryllium and aluminum. This indicates that me...
متن کاملChanges in crystallographic orientation of thin foils of palladium and palladium alloys after the absorption of hydrogen
The adsorption/absorption of hydrogen at room temperature by palladium, 16% silver-palladium and 5% ruthenium-palladium foils was studied using thermal desorption spectroscopy. Hydrogen readily diffused in the palladium and desorbed as one broad peak at about 650 K. Hydrogen also diffuses in the 16% silver-palladium foil and in the 5% rutheniumpalladium foil but with a smaller diffusion constan...
متن کاملQuantitative evaluation of radiation damage to polyethylene terephthalate by soft X-rays and high-energy electrons.
The chemical changes and absolute rates in radiation damage to polyethylene terephthalate (PET) caused by soft X-rays and energetic electrons have been measured using a scanning transmission X-ray microscope (STXM). Electron beam damage at two different dose rates and a range of doses was performed in an 80 keV transmission electron microscope (TEM). The STXM beam was used to create damage patt...
