The parameters of stimulated lasing in diffuse discharges formed in mixtures of helium and fluorine in a strongly inhomogeneous electric field are investigated. Lasing is obtained in the visible and VUV spectral regions on the transitions of fluorine atoms and molecules. It is shown that lasing in He – F2 mixtures at a wavelength of 157 nm continues for several half-periods of the discharge current. Due to the homogeneity of the diffuse discharge, the maximum lasing efficiency of the F2 laser is 0.15 %, which corresponds to the efficiency of this type of lasers pumped by pre-ionised transverse volume discharges.

Xenon emission in the spectral range of 120 – 800 nm upon excitation by subnanosecond voltage pulses is investigated. Excitation is performed using diffuse and spark discharges in an inhomogeneous electric field at a xenon pressure ranging from 0.3 to 3 atm. It is shown that xenon excitation by a series of successive 0.7-ns voltage pulses with a pause of 30 ns leads to a decrease in the second-continuum radiation intensity by the second and subsequent voltage pulses and an increase in the first-pulse afterglow intensity. It is confirmed that in the case of a pulsed diffuse discharge, the second continuum of xenon dimers, which is used to generate laser and spontaneous radiation in the VUV spectral region, makes the largest contribution to the radiation energy. Broadband radiation in the visible range (λ > 400 nm) is found to occur when the discharge is constricted. The obtained results indicate that the influence of the dynamic displacement current on the pin-diode caused a measurement error in the papers by V.I. Baryshnikov et al., who did not record the second-continuum radiation from xenon excited by a short homogeneous discharge.

An ion source was developed for transporting space debris to the disposal orbit by acting on such objects with an intense ion beam injected from a “service” spacecraft. The ion source differs by weakly diverging ion beam, radio-frequency inductive discharge, and a three-electrode slit ion-extraction system with quasi-Pierce geometry.

This scientific article deals with the problem of the use of the hermeneutic method of obtaining knowledge of legal phenomena. The purpose of the article is to show the potential of the hermeneutic method in the field of law.  In the furtherance of this goal, the following objectives were set: 1) to justify the significance of the methodological basis of jurisprudence; 2) to consider the concept of hermeneutics in the historical aspect (views of Aristotle, Wilhelm Diltey, Friedrich Schleiermacher, Friedrich Nietzsche, Hans-Georg Gadamer, Max Weber and others); 3) to analyze the views of domestic scientists who justifying the necessity of using of the hermeneutic method by the study of legal phenomena (Djangir Abbasovich Kerimov, Mikhail Mikhailovich Rassolov, Petr Moiseyevich Rabinovich, Vitaly Andreevich Suslov, Ilya Lvovich Chestnov); 4) to show weak points of the hermeneutic method in jurisprudence, arguments of opponents of this approach (Vladimir Mikhailovich Syryh, Igor Yurevich Kozlikhin, Vyacheslav Nikolayevich Zhukov and others). The result of the conducted research were the following provisions: 1) without denying some fruitfulness of the metaphysics which is the basis of the analyzed method, we notice that the hermeneutics method is not applied practically in the law because there is no the corresponding technique and it is replaced with a historical method of interpretation of legal norms. In conclusion, it should be stressed that even those scientists who placed certain research hopes on the legal hermeneutics have now begun to doubt its potential, believing that this approach of the study of the law as an independent one has not yet taken place.
