New methods of isotope separation

Energy Approach to Atoms in a Laser Filed and Quantum Dynamics with Laser Pulses of Different Shape

“…To number of the very actual problem of modern nuclear technology, quantum and photoelectronics is related a search of the effective methods for isotopes and nuclear isomers separation and obtaining especially pure substances at atomic level (Letokhov, 1969(Letokhov, , 1977Letokhov et al, 1975Letokhov et al, -1977Letokhov et al, , 1979Letokhov et al, , 1980Letokhov et al, , 1985Letokhov et al, , 1986Letokhov et al, , 1992Letokhov et al, , 1990Basov et al 1969Basov et al , 1977Prokhorov, 1979Janes et al, 1975;Solarz et al, 1976;Lisitsa, 1977;Singh et al, 1994;Duarte et al, 1990Duarte et al, , 2002Duarte et al, , 2003Duarte et al, , 2010Bokhan et al, 2006;etc). The basis for its successful realization is, at first, carrying out the optimal multi stepped photo-ionization schemes for different elements and, at second, availability of enough effective UV and visible range lasers with high average power (Letokhov, 1977(Letokhov, , 1979(Letokhov, , 1983etc).…”

Intensification of syngas ignition through the excitation of CO molecule vibrations: a numerical study

“…It is believed that the approach based on the excitation of reacting molecules to intensify the chain mechanism in a combustible mixture is much more effective and is free from some essential disadvantages. Note that the use of resonance laser radiation for the initiation of chemical reactions through the excitation of vibrational degrees of freedom of molecules was suggested in the early 1970s [12,13]. This method is based on the fact that when molecules excited to their lower vibrational levels interact they can 'climb' up the energy levels until they reach the activation energy (E a ) of a given reaction via intramode vibration-vibration energy exchange.…”
