Tunnel junctions containing Sn particles inside the oxide barrier have been prepared. Tunneling currents via these particles are measured. Interpretation is given in terms of the effect of fluctuations on the tunneling density of states in a “zero-dimensional” superconductor. 相似文献

Summary According to the sequential decision theory, one is directed to; (i) stop when the posterior distribution, having been successively
watched, frist enters the domain in which by stopping he loses less, and then (ii) take that action which gives him the least
loss averaged w.r.t. the current posterior distribution (Blackwell-Girshick [1], p. 254).
For some reasons we don't know, however, the successive behavior of posterior distribution never draws the full attention
of statisticians and probabilists, though some of them have developed the asymptotic theory. As far as the sequential decision
theory is concerned, however, the asymptotic behavior tells us nothing, since the stopping rule is only related to finite
time.
Toe compute the posterior distribution time by time is a laborious task. But to site all possible posterior distributions
sometimes facilitates our manipulation of the sequential decision problem. This paper proposes some methods.

The B-type ν1 fundamental band of chlorine dioxide has been observed with the resolution of 0.06 cm?1, and several molecular parameters have been derived for the 35ClO2 isotopic species. The spectrum has been partially resolved by a tunable diode laser, and many doublet structures have been observed providing sufficient data to determine the spin-rotation interaction constants. 相似文献

It has been shown that a Raman line of a nontotally symmetric vibration (b1g, b2g, or a2g) of a metalloporphyrin (D4h) can be caused, not only by a vibronic coupling between the first () and second () excited electronic states but also by a vibronic coupling within one of the electronic states (let us call the former the QS mechanism and the latter the QQ and/or SS mechanism). A simple formulation has been made for each of those different mechanisms, so that a numerical calculation can be made of the excitation profile of a Raman scattering for a given set of coupling constants and damping factors. Next, the result of an examination is given of the excitation profile of the Raman scatterings of some of the b1g, b2g, and a2g vibrations of nickel octaethylporphyrin and nickel octaethyltetrachloroporphryin. Most of the Raman lines of these nontotally symmetric vibrations show a resonance effect only in the Q-band () region but not in the Soret-band () region. On the basis of this fact, it has been suggested that those Raman lines are caused mainly by the QQ mechanism rather than the QS mechanism. The observed vibrational structure of an excitation profile also seems to support this suggestion. 相似文献

To explore the capability of unstructured mesh to simulate detonation wave propagation phenomena, numerical simulation of
H2/air detonation using unstructured mesh was conducted. The unstructured mesh has several adv- antages such as easy mesh adaptation
and flexibility to the complicated configurations. To examine the resolution dependency of the unstructured mesh, several
simulations varying the mesh size were conducted and compared with a computed result using a structured mesh. The results
show that the unstructured mesh solution captures the detailed structure of detonation wave, as well as the structured mesh
solution. To capture the detailed detonation cell structure, the unstructured mesh simulations required at least twice, ideally
5times the resolution of structured mesh solution.

A single‐crystal momentum‐resolved resonant inelastic X‐ray scattering (RIXS) experiment under high pressure using an originally designed diamond anvil cell (DAC) is reported. The diamond‐in/diamond‐out geometry was adopted with both the incident and scattered beams passing through a 1 mm‐thick diamond. This enabled us to cover wide momentum space keeping the scattering angle condition near 90°. Elastic and inelastic scattering from the diamond was drastically reduced using a pinhole placed after the DAC. Measurement of the momentum‐resolved RIXS spectra of Sr2.5Ca11.5Cu24O41 at the Cu K‐edge was thus successful. Though the inelastic intensity becomes weaker by two orders than the ambient pressure, RIXS spectra both at the center and the edge of the Brillouin zone were obtained at 3 GPa and low‐energy electronic excitations of the cuprate were found to change with pressure. 相似文献
