A systematic study of three-nucleon force (3NF) effects in break-up reactions has been carried out at KVI at several energies. In this article, the p + d → p + p + n reaction with a polarized-proton beam of 190?MeV will be discussed. The experiment was performed by exploiting a new detector called BINA. Some results for high-precision vector analyzing powers and differential cross sections are presented and compared with state-of-the-art Faddeev calculations with or without 3NF. 相似文献

Attachment line boundary layer transition on swept cylinders is studied in a low enthalpy hypersonic wind tunnel at M
∞=7.14. Sweep angles of 60° and 70° are used and transition is detected by means of heat flux measurements. The influence on
attachment line transition of single 2D-roughness elements, in the form of tripwires or slots, as well as 3D obstacles is
determined and the results are analyzed with respect to Poll’s criterion.

Mg atoms were vaporized into a fast flowing Ar carrier stream and then excited by an ac discharge. Downstream of the discharge in the afterglow region metastable Mg (3P) atoms were reacted with vaporized metals. The resultant chemiluminescence consisted of metal atom resonance lines and continuous emission bands of the molecule KMg. 相似文献

A mixture of Li and Mg vapors at 900°C was optically pumped at 488 nm by an Ar+ ion laser. The resulting Li2 fluorescence and LiMg* excimer chemiluminescence intensities were analyzed to determine rate constants for the reactions Li2(B1π) + Mg → LiMg* + Li and LiMg* + Li → Li2(a3π) + Mg and the radiative decay rates of Li2(B1π) and LiMg*. 相似文献

Laser amplification by stimulated emission in the 001-100 vibrational-rotational band of CO2 has been continuously excited by transfer from the products of the oxidation of alkaline earth metal vapors in N2O. The sensitive detection of gain transverse to a 1 cm diameter flame was accomplished by intracavity measurements in a conventional CO2-EDL with the aid of two frequency modulation and synchronous detection. 相似文献

Surface adsorbates and surrounding matrix species have been demonstrated to affect the properties of nanoscale ferroelectrics and nanoscale ferroelectric composites; potentially counteracting performance losses that can occur in small particle sizes. In this work, the effects of nonpolar oleic acid (OA) and polar tetrafluoroborate (BF4−) ligand capping on the surface of various sizes of BaTiO3 nanocubes have been investigated with combined neutron diffraction and neutron pair distribution function (PDF), density functional theory (DFT), and ab initio molecular dynamics (AIMD) methods. The low real space PDF region provides an unobstructed view of rhombohedral (split short and long) Ti−O distances in BaTiO3 nanocubes, mimicking the well-established order-disorder local structure found in bulk BaTiO3. Interestingly, the intermediate-range order in nanocubes is found to be orthorhombic, rather than tetragonal. It is concluded that polar ligands adsorbed at BaTiO3 surfaces stabilize the correlation length scale of local rhombohedral distortions in ferroelectric nanoparticles relative to nonpolar ligands. 相似文献

Recent disruptions in the molybdenum-technetium generator supply chain prompted a review of non-reactor based production methods for both 99Mo and 99mTc. Small medical cyclotrons (E p ~ 16–24 MeV) are capable of producing Curie quantities of 99mTc from isotopically enriched 100Mo using the 100Mo(p,2n)99mTc reaction. Unlike most other metallic target materials for routine production of medical radioisotopes, molybdenum cannot be deposited by reductive electroplating from aqueous salt solutions. To overcome this issue, we developed a new process for solid molybdenum targets based on the electrophoretic deposition of fine 100Mo powder onto a tantalum plate, followed by high temperature sintering. The targets obtained were mechanically robust and thermally stable when irradiated with protons at high power density. 相似文献

A useful and rapid access to libraries of N‐arylbenzo[b]furo[3,2‐d]pyrimidin‐4‐amines ( 1 ) and their novel benzo[b]thieno[3,2‐d]pyrimidin‐4‐amine analogues ( 2 ) was investigated for the first time. Title compounds were obtained via microwave‐accelerated condensation and Dimroth rearrangement of suitable anilines with N′‐(2‐cyanaryl)‐N,N‐dimethylformimidamides obtained by reaction of benzo[b]furane and benzo[b]thiophene precursors with N,N‐dimethylformamide dimethyl acetal. This work also demonstrates that well‐controlled parameters offer comfortable use of microwave technology and are both safe and beneficial to the environment. Some products obtained in this article exhibit interesting in vitro antiproliferative effects. 相似文献
