Time-resolved coherent anti-Stokes Raman-scattering (CARS) measurements are carried out for iodine (I2) in solid krypton matrices. The dependence of vibrational dephasing time on temperature and vibrational quantum number v is studied. The v dependence is approximately quadratic, while the temperature dependence of both vibrational dephasing and spectral shift, although weak, fits the exponenti...
We present an experiment where Ramsey-type spectroscopy is applied to autoionizing states of krypton by using the ninth harmonic (88 nm) of a femtosecond Ti:sapphire laser. The ionization process, detected by an electron-energy spectrometer, shows the characteristic quantum interference pattern. The behavior of the fringe contrast compares favorably with a simple essential-state model, whose pa...
We present vapor pressure and high-resolution heat-capacity measurements of multilayer krypton films adsorbed on graphite. We have found a complex phase diagram including reentrant layering transitions for coverages higher than three layers. The third layering transition does not end in a condensation critical point as was previously expected. The second-layer melting transition is preceded by ...
A two-dimensionally imaging spectrometer system was employed to measure spatial variations in the intensities of emission lines in a Cu-Mn-Ni alloy sample when they were excited from a laser-induced plasma with krypton gas. The emission zone of these lines shrank and had greater emission intensities with increasing gas pressure, and the intensities of their background also became more intense. ...
We have developed a synchrotron-based, time-resolved x-ray microprobe to investigate optical strong-field processes at intermediate intensities (10(14) - 10(15) W/cm2). This quantum-state specific probe has enabled the direct observation of orbital alignment in the residual ion produced by strong-field ionization of krypton atoms via resonant, polarized x-ray absorption. We found strong alignme...
The need to improve the understanding of properties cement-based materials calls for development tools visualizing and quantifying chemical reactions flows fluids within them. In this paper, we report results an experimental study where a sample fractured cement-paste was subjected injection (krypton, CO2 water) imaged simultaneously by X-ray computed tomography (CT). Initial porosity estimated...
