The lifetime of negative muons has been measured in 50 elements plus 8 isotopes. For light the accuracy 2 to 3 ns is a significant improvement over most previous measurements. In heavier 1 ns, which comparable to, or better than, results, with reasonable agreement cases. $^{18}\mathrm{O}$, Sc, Dy, and Er there were no data. total capture rates have deduced compared various calculations.
Bunched electron waves in CdS ultrasonic amplifier are formed by two kinds of space charge waves, that is, mobile due to free electrons and bound at trapping centers. When the product relaxation time angular frequency sound is an order unity, phase difference between trapped becomes appreciable, fraction, f , which gives ratio total charges, takes a complex form. Under this condition dependence amplification factor, α', deduced use on applied dc voltages considerably unsymmetrical about...
A direct search has been made for supermassive relics (heavier than about ${10}^{12}$ GeV/${\mathit{c}}^{2}$) with a 2000-${\mathrm{m}}^{2}$ array of CR-39 track-etch detectors deployed underground 2.1 yr.

A self-consistent calculation is performed for the study of magnetic-field effects on energy level structure quantum wires formed by a split gate technique at GaAs/AlGaAs heterostructures. The potential and dispersion exhibit dramatic change when subband depopulation occurs in high magnetic fields.
Group III-V compounds are very important as the materials of semiconductor devices. Stable structures monolayers group binary have been discovered by using first-principles calculations. The primitive unit cell is a rectangle, which includes four group-III atoms and group-V atoms. A atom its three nearest-neighbor placed on same plane; however, these connections not sp2 hybridization. bond angles around less than angle sp3 structure GaP an indirect transition semiconductor, while GaAs, InP,...
The branching ratio for the reaction ${\ensuremath{\pi}}^{\ensuremath{-}}d\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}\mathrm{nn}$ has been measured first time by stopping ${\ensuremath{\pi}}^{\ensuremath{-}}$ in a liquid-deuterium target and detecting two decay $\ensuremath{\gamma}'\mathrm{s}$ large NaI detectors.

In the preceding paper (arXiv: 1103.0329 [quant-ph]) we treated Jaynes–Cummings model with dissipation and gave an approximate solution to master equation for density operator under general setting by making use of Zassenhaus expansion. However, obtain a compact form (which is in complicated infinite series) very hard when initial condition given. To overcome this difficulty develop another approach some

This paper presents the new fundamental equations of electro-acoustic conversion for N -pair IDT by using force factors. From these equations, simplified three-port equivalent circuits have been derived. As an application, in case that one two acoustic ports is connected with characteristic impedance, two-port also derived much simpler forms.
