ABSTRACT
We elucidate the major mechanism of microparticle removal in the megasonic cleaning process through the direct visualization experiments. It is revealed that particles sitting on solids are removed by adjacent microbubbles that oscillate near the substrates and exert interfacial and pressure gradient forces on the particles. Other pressure and streaming effects are shown to be too weak to detach the particles.

    Holes burnt into the absorption spectrum of terrylene in hexadecane have quite unusual features: spectral diffusion behavior under thermal cycles shows a narrowing regime at very low temperatures (2–5 K) followed by a plateau region (up to about 13 K) and a broadening regime (T>13 K)....

    Quantitative investigations of the hydrogen-like exciton B series in the absorption spectra of the β-ZnP[sub 2] crystal for various wave vector directions and polarization states of radiation are conducted. It is shown that the B spectrum constitutes a single orthoexciton series with S-type...

    The spectrum of the modulus and the imaginary part of the third order nonlinear optical susceptibility χ(3) of polydiacetylene was studied over the range 750–1000 nm by a combination of two-photon absorption and degenerate four wave mixing measurements. A peak in the two-photon...

    Using recent experimental data for the Hartley band absorption spectrum obtained at low temperature, a vibrational analysis of the discrete structure in the spectrum is given. It is found that all of the peaks in the range 238–292 cm can be assigned to transitions between the (0,0,0)...

    A self-consistent effective medium theory of the electronic absorption spectra of tightly bound dipolar excitons in simple fluids is developed within the adiabatic picture. The theoretical approach is based on the isomorphism between the path-integral formulation of quantum theory and classical...

    We report the use of picosecond transient absorption spectroscopy to directly observe the dynamics of formation, tunneling, and subsequent cooling of the n=1, Γ(3/2) exciton in condensed xenon over a density range of 0.10 to 1.8 g/ml. At lower densities, only Xe*2 excimers are formed, which...

    Exciton absorption spectra in high-quality β-ZnP[sub 2] single crystals have been investigated at T=1.7 K for various directions of the wave vector and various polarization states of the radiation. It has been unambiguously established that the additional high-energy A series, which in some...

    It is shown that, because the shape of the exciton absorption curve in crystalline TlGaS[sub 2] is described by the Fano antiresonance profile, the experimentally observed exciton peak corresponds to a modified state which is the result of the configuration interaction of a discrete state...
