Diffusive motion of an Li+ion in the solid solution Li4?x(PO4)x(SiO4)1?x (0 ≦ x ≦ 0.35) was studied by 7Li pulsed nmr between ? 70 and 440°C. Activation energies for an Li+ ion diffusion decreased monotonically with increasing x in the composition. These values are smaller than those reported from the measurement of ionic conductivity. Discrepency seems to result from the local nature of an Li+ diffusion observed by nmr contrary to the long-range one in the ionic conduction. 相似文献

Proton polarization and differential cross section for the (3He,p) reaction on 6Li and 9Be at 14 MeV
Angular distributions of the proton polarization and the differential cross section have been measured for the reaction (3He, p) initiated by 14 MeV incident 3He particles and proceeding to the ground and the first excited states of the final nuclei 8Be and 11B. Large polarization values were observed, especially for the 9Be(3He, p)11B reaction leading to both the ground and the first excited states in 11B. The experimental results have been analysed in terms of a two-nucleon transfer spindependent distorted-waves theory using finite-range formalism and including corrections due to the non-locality of the optical potentials. A proper coherent summation over L and S, whenever necessary was included in the DWBA calculations of the polarization and the differential cross section as implied by the presence of the spin-orbit terms in the optical-model potentials used to generate the distorted waves. 相似文献

The anisotropy of the crystalline relaxation (α relaxation) in oriented poly(vinylidene fluoride) in crystal form II has been studied. The dielectric increment Δε is analyzed on the basis of the two-site model. A linear relation between Δε/χξ and cos2θ is obtained, where χ is the degree of crystallinity, ξ is the ratio of the internal field to the applied field, and θ is the angle between the applied electric field and the molecular axis. The dipole moment changes direction only along the molecular axis in the relaxation in crystal form II; the molecular motion cannot be explained by chain rotation around the molecular axis. Possible models for the α relaxation are proposed: change in conformation with internal rotation can occur in the crystalline chains, and defects in the crystalline regions play an important role in the α relaxation. 相似文献

The differential absorption method with the conventional CO2 laser is discussed for the detection and monitoring of ozone in ambient atmosphere. By using the P(14) line in the (00°1 to 02°0) and the R(16) line in the (00°1 to 10°0) band, the measurement of ozone was made in a field. As an experimental result, the minimum detectable concentration of 0.15 ppm was obtained with the system, and the concentration of 0.2 ppm was measured in a photo-chemical smog. 相似文献

Evaporation residue cross sections in the 16O+238U reaction were measured for the energy range from above- to extreme sub-barrier. The cross sections are reproduced by a statistical model calculation, for which partial cross sections are calculated by a coupled-channel model taking into account the prolate deformation of 238U. Complete fusion was observed in the collision of the projectile with the tips of the 238U target, in the same way as the side collision. 相似文献
