It is shown that plasma-chemical processes involving ionized and excited particles can make the main contribution to the pumping
of energy into vibrations of carbon monoxide molecules. It is noted that the use of helium as a buffer gas in the active laser
medium is not optimal. The employment of argon instead of helium permits a 1.5-fold increase in the efficiency of the pumping
of energy into carbon monoxide molecules and an order-of-magnitude decrease in the threshold energy for pumping the active
medium.

Single crystals of lead titanate PbTiO3 doped with silicon, calcium, chromium, manganese, cobalt, nickel, copper, zinc, and cadmium were grown. The compositions and crystallographic parameters of the crystals were studied. The lowest distribution coefficients of dopants between PbTiO3 crystals and flux were observed with Mn+2 and Co+2 and the highest, with Ca+2. Doping with niobium leads to the formation of solid solutions with the pyrochlore structure A2B2O7 and even higher distribution coefficient. A correlation was found between dopant concentrations and crystal cell parameters. 相似文献

The present status of calculations of the hyperfine splitting and the transition probability between the hyperfine splitting
components in hydrogen and lithium like ions is discussed. The results of the calculations are compared with recent experimental
data. A special attention is focused on the hyperfine splitting in hydrogen like lead and lithium like bismuth. It is shown
that the theoretical prediction for the ground state hyperfine splitting in lead based on the single particle nuclear model
for the Bohr-Weisskopf effect is in fair agreement with experiment. The theoretical prediction for the ground state hyperfine
splitting in lithium like bismuth is improved due to more accurate calculations of the interelectronic interaction, QED, and
nuclear corrections.

Mesoporous TiO2 has been obtained by template synthesis. The introduction of a surfactant in the hydrolysis of tetrabutoxytitanium in aqueous ethanol allows the structure of the resulting material to be controlled. The amorphous TiO2 resulting from hydrolysis turns into anatase on being calcined at 300°C. As determined by X-ray diffraction, the anatase crystallite size is 70 nm in the presence of the highest surfactant concentration examined and 210 nm in the absence of a surfactant. Amorphous materials have been characterized by electron microscopy and differential thermal analysis. The ultimate benzene adsorption value has been determined for calcined mesoporous TiO2. 相似文献

Strong few-cycle light fields with stable electric field waveforms allow controlling electrons on time scales down to the attosecond domain. We have studied the dissociative ionization of randomly oriented DCl in 5 fs light fields at 720 nm in the tunneling regime. Momentum distributions of D(+) and Cl(+) fragments were recorded via velocity-map imaging. A waveform-dependent anti-correlated directional emission of D(+) and Cl(+) fragments is observed. Comparison of our results with calculations indicates that tailoring of the light field via the carrier envelope phase permits the control over the orientation of DCl(+) and in turn the directional emission of charged fragments upon the breakup of the molecular ion. 相似文献
