Isotope sepn. was demonstrated following the selective IR laser-induced photodissocn. of van der Waals clusters in a free jet. Irradn. of a natural abundance mixt. of SF6 isotopomers dild. in Ar with a 20-W cw CO2 laser gave overall enrichment factors >1.1 ...
New luminescence centers can be generated by irradiating AlxGa1-xAs structures with focused light from a CW Kr-ion laser operated at 647 nm. The luminescence centers are generated at a laser power density of 0.5 MW/cm2. Regions as small as 0.8 μm wide a ...
A new luminescence band is observed in optically pumped Ge-doped (Al,Ga)As multilayer structures, that were previously subjected to laser irradiation. The band is shifted by 90 meV to longer wavelength with respect to the luminescence peak of the unexposed ...
The efficiency of classical gas-dynamic isotope sepn. can be strongly improved with the aid of a relatively weak IR laser. Irradn. in the collisional region of a free jet of SF6 dild. in Ar with a 20-W CO2 laser leads to an increase in the overall enrichme ...
A mol. beam mass spectrometer was constructed to study the formation of van der Waals clusters over a wide mass range. Using this app. (SF6)m was detected with 1 ? m ? 100 in the adiabatic expansion of SF6. By irradiating the SF6 jet with a continuous-wave ...
