With this spectrometer, a charged particle experiences four separate interactions with the CCDs and ranging filters: this allows the incident particle energy to be overdetermined and the particle to be uniquely identified. Furthermore, because the CCD has small picture elements ( 20 μm), pulse ...
28 A particle has a charge of +2.0 m C and is in a vertical uniform electric field. An electric force of1.0*10^(-2) N acts upwards on the particle.What is the electric field strength? D A 0.20V m-1 downwards B 0.20 V m-1 upwards C 5.0V m-1 downwards D 5.0V m-1 upwards...
It consists of a chamber provided with two electrodes coupled to an electric potential. Gas ions created by the radiation are attracted to the respective electrodes of opposite charge, causing an electric current (called the ion current) to flow between the electrodes. The ion current is ...
These correlations create additional binding of multivalent counterions to the macroion surface with binding energy larger than kBT. As a result even for a moderate concentration of multivalent counterions in the solution, their total charge at the surface of the macroion exceeds the bare macroion...
A theoretical formula to predict the time-varying net charge of a particle was derived based on Coulomb's law and ion drift- diffusion equation. The calculated results showed good agreement with the experimental results. Theoretical analysis show that particle charge decays exponentially with time, ...
A new method was developed to measure local particle deposition patterns in a full-scale multisectional replica of a human nasal airway. Monodisperse dioctyl sebacate aerosol particles, labeled with the fluorescent dye Nile Red, were deposited in a human nasal airway model by drawing the aerosol th...
Notice that the “−1 particle” should not be confused with an anti-particle. In contrast to the latter, which differs from its particle only with charge, a “−1 particle” is unique in that all its properties are negative when probed by weak measurement. This is an intriguing predict...
,Hartmann,and,A E.摘要: Energy spectra of charged particles (p, d, t, 3He, α) emitted following the absorption of stopped π− in 12C, 59Co and 197Au have been measured. The results are compared with results from neutron spectroscopy and discussed in the context of the quasi-...
Effects of "regular" and stochastic charge variations are considered. It is shown that whilst regular variations generally enhance the damping of horizontally propagating dust lattice waves, they can also cause an instability in the vertical oscillations of single particles. The stochastic charge ...
19. Authon use the photon as a particle which explain the wave phenomenon of the photon, and prove the photon carry the weak charge from the prism-photons chromatic dispersion and a circular hole -photon diffraction. 作者利用光的粒子性解释了光的波动现象,从三棱镜光的色散和园孔光的衍射证明了光...
