15 صفحه اولX-Ray and Neutron Reflectivity
re = 2.818 × 10−15m is the classical electron radius, ρe is the electron density of the material, and μx is the absorption length. With δ > 0 we find that n < 1, which leads to the phenomenon of so-called total external reflection for incident angles αi below the critical angle αc = √ 2δ. Typical values for δ are 10−5 . . . 10−6, and thus αc is in the range of 0.1 ◦ . . . 0.5◦. For simplicity, ...
متن کاملGas Flow Calculations and Measurements for a Gas Stopping Cell
Along with several other nuclear physics laboratories around the world, the NSCL has undertaken the challenge of stopping a radioactive ion beam in order to make low-energy beams for experiments that require nearly thermal beam energies (precision mass measurements, laser spectroscopy, etc.). As part of the LEBIT (Low Energy Beam and Ion Trapping) Project at the NSCL, a gas stopping station is ...
متن کاملNeutron Reflectivity and Grazing Angle Diffraction
Over the last 10 years, neutron reflectivity has emerged as a powerful technique for the investigation of surface and interfacial phenomena in many different fields. In this paper, a short review of some of the work on neutron reflectivity and grazing-angle diffraction as well as a description of the current and planned neutron rcflectometers at NIST is presented. Specific examples of the chara...
متن کاملSilk layering as studied with neutron reflectivity.
Neutron reflectivity (NR) measurements of ultrathin surface films (below 30 nm) composed of Bombyx mori silk fibroin protein in combination with atomic force microscopy and ellipsometry were used to reveal the internal structural organization in both dry and swollen states. Reconstituted aqueous silk solution deposited on a silicon substrate using the spin-assisted layer-by-layer (SA-LbL) tec...
