Observation of the fine structure for rovibronic spectral lines in visible part of emission spectra of
For the first time in visible part of the emission spectrum the pseudo
doublets representing partly resolved fine structure of rovibronic lines have
been observed. They are characterized by splitting values about 0.2 cm
and relative intensity of the doublet components close to 2.0. It is shown that
they are determined by triplet splitting in lower rovibronic levels of various
electronic transitions. It is proposed to use
an existence of such partly resolved fine structure patterns for identification
of numerous unassigned spectral lines of the molecule coming from great
variety of triplet "gerade" electronic states to vibro-rotational levels of the
state.Comment: 6 pages, including 2 figures and 1 table; submitted to Phys.Rev.Let
A Modified Scheme of Triplectic Quantization
A modified version of triplectic quantization, first introduce by Batalin and
Martnelius, is proposed which makes use of two independent master equations,
one for the action and one for the gauge functional such that the initial
classical action also obeys that master equation.Comment: 8 page
UV continuum emission and diagnostics of hydrogen-containing non-equilibrium plasmas
For the first time the emission of the radiative dissociation continuum of
the hydrogen molecule ( electronic
transition) is proposed to be used as a source of information for the
spectroscopic diagnostics of non-equilibrium plasmas. The detailed analysis of
excitation-deactivation kinetics, rate constants of various collisional and
radiative transitions and fitting procedures made it possible to develop two
new methods of diagnostics of: (1) the ground state
vibrational temperature from the relative intensity
distribution, and (2) the rate of electron impact dissociation
(d[\mbox{H_{2}}]/dt)_{\text{diss}} from the absolute intensity of the
continuum. A known method of determination of from relative
intensities of Fulcher- bands was seriously corrected and simplified
due to the revision of transition probabilities and cross sections of
electron impact excitation. General considerations are illustrated
with examples of experiments in pure hydrogen capillary-arc and H+Ar
microwave discharges.Comment: REVTeX, 25 pages + 12 figures + 9 tables. Phys. Rev. E, eprint

A proposal for a generalized canonical osp(1,2) quantization of dynamical systems with constraints
The aim of this paper is to consider a possibility of constructing for
arbitrary dynamical systems with first-class constraints a generalized
canonical quantization method based on the osp(1,2) supersymmetry principle.
This proposal can be considered as a counterpart to the osp(1,2)-covariant
Lagrangian quantization method introduced recently by Geyer, Lavrov and
M\"ulsch. The gauge dependence of Green's functions is studied. It is shown
that if the parameter m^2 of the osp(1,2) superalgebra is not equal to zero
then the vacuum functional and S-matrix depend on the gauge. In the limit the gauge independence of vacuum functional and S - matrix are restored. The
Ward identities related to the osp(1,2) symmetry are derived.Comment: Revised version. To appear in Mod.Phys.Lett.
