Discussion of the parity violation and the break of the time-reversal invariance m diatomic molecules has continued for a number of years Experiments an the TIF molecule gave one of the most stringent limits on the electric-dipole moment of the proton and on the T-violating nuclear forces, At present, a new generation of experiments wilh paramagneticdiatomic molecules is underway. These experiments are aimed mainly at the search for the electric-dipole-moment of the electron.In this topical review we enamine theoretical aspects of parity non-conservation in diatomic molecules. We focus on molecular theory leaving aside the nuclear pan of the problem. In this approach the nucleus is characterized by he number of P-odd and P, T-odd moments, namely anapole moment, Schiff moment and magnetic quadrupole moment. Molecular theory has to link lhese moments to the experimentally measured quantities. such as frequency shifts, etc. The other possible sources of the parity non-conservation in molecules are the electronnuclear neutral c m n t interactions and the electricdipole moment of the electron. They are also discussed in lhis review. ' Rizlewicz er al(1982). g Van Zee er al(1978). Knight er al(1981).

“…The new double-nozzle technique for in-gas-jet resonance ionization laser spectroscopy that we propose here is based on the idea of gas dynamic cooling of lowenergy molecular and ion beams. This idea has been proposed for the first time in 1979 [52,53] and described also e.g. in [5,39,[54][55][56][57][58][59][60][61].…”

“…То show experimentally the feasibility and effectivity of the described gas dynamic method, a setup of a gas dynamic molecular beam source has been constructed in the middle of 1980s in the Leningrad Nuclear Physics Institute (LNPI) in Gatchina [56,57]. In result of experimental investigations, it has been obtained the effective cooling of hot lead iodine (PbJ) molecular beam in the supersonic nitrogen jet from 900 K down to 20 K, and it was important part of our PhD work [54]. Notice, that the two-atomic molecules PbJ are free radicals, which produced via thermal decomposition of three-atomic molecules PbJ2 inside the separatly heated thin quartz capillary installed into the inner tube of the supersonic nozzle shown in Figure 12.…”

In this paper a new double-nozzle technique for in-gas-jet laser resonance ionization spectroscopy is proposed. The functionality of this new technique we explored by detailed gas dynamic and Monte Carlo atom-trajectory simulations, which results are presented and discussed. The results of similar computer simulations for JetRIS setup (as a typical representative of the conventional nowadays in-gas-jet technique) are presented and discussed as well. The direct comparison of calculation results for proposed new technique with the conventional one shows that the double-nozzle technique has many advantages compared with that one used in the JetRIS setup at GSI for future high-resolution laser spectroscopic study of heaviest elements. To fully implement the proposed new technique to all existing (or under construction) setups for in-gas-jet laser resonance ionization spectroscopy, it will be enough just replace the used their supersonic nozzle by the miniature double-nozzle device described in the paper.
