From 27th October to 4th November 2019 Ivke visited NIFS (National Institute for Fusion Science) in Toki, Japan, as a member of University of Belgrade delegation headed by rector Ivanka Popović, who signed an Agreement of collaboration between NIFS and University of Belgrade.
Ivke, Bratislav Obradović (Faculty of Physics), Milan Rajković (Institute of Nuclear Sciences Vinca) and Milica Ilić (Faculty of Mechanical Engineering) had a fruitful discussions with Japanese colleagues and made plans for future common projects.
- ELI attosecond in Szeged (HU);
- High voltage laboratory in Brno (CZ), where they work with 120 kA currents and 2 MV voltages;

- ELI beams and Institute of Plasma Physics in Prague (CZ), latter one showed him COMPASS tokamak and PALS ion laser.
We are proudly presenting published article by Biljana, her second article this year as the first author. However, the significant contribution of co-authors should not overseen. The article is entitled “Forbidden component of the Be II 436.1 nm line recorded from pulsed gas discharge plasma” and published by Europhysics Letters journal.
Yesterday, the Laboratory hosted Dr. Predrag Ranitović, who held an open lecture at Institute of Physics Belgrade. The lecture title was “Attosecond Coherent Control of Atomic and Molecular XUV and X-Ray Absorption Processes by Intense Laser Radiation”.
Recent breakthroughs in the ultrafast lasers development have allowed for the opening of new horizons in the ultrafast experimental and theoretical AMO physics. Following these advances, table-top light sources have provided novel ways to achieve a real-time manipulation of the correlated electron/nuclear wavepacket dynamics by means of attosecond XUV and femtosecond IR radiation [1-6]. However, more than fifteen years upon the birth of attosecond physics, and after the Nobel Prize Award for femtochemistry, the concept of attosecond chemistry has not yet been fully realized. In this talk, I will introduce the basic principles of the strong laser-field ionization and generation of attosecond XUV/X-Ray radiation, and show how the attosecond VUV and XUV light sources can be used to coherently manipulate molecular dynamics by means of electron wave packet interferometry [7-9]. The use of attosecond VUV pulse-trains to coherently excite and control the outcome of a simple chemical reaction in a deuterium molecule, in a nonBorn-Oppenheimer regime, presents intriguing new possibilities for bridging the gap between the attosecond physics and attochemistry . Furthermore, I will discuss very recent results that extend the use of the attosecond table-top techniques to the soft X-Ray regime in the water window .

All members of the laboratory participated at the 29th Summer School and International Symposium on the Physics of Ionized Gases (SPIG 2018) held in Belgrade (Serbia). Again, Prof. Кonjević held the introductory talk. Ivke was member of the Scientific Committee for the third consecutive time. Marijana, Milica and Marko each presented the poster titled “Underwater Ablation with Two Different Laser Wavelength”, “Nanoparticles on a Sample Surface as Laser Induced Breakdown Spectroscopy Enhancers” and “Current Distribution in an Experiment of Z-Pinch with Pre-Embedded Axial Magnetic Field”, respectively. While Biljana and Miloš presented the progress reports on “Beryllium spectral line studies in the presence of beryllium dust” and “Studies or Runway Electrons in COMPASS Tokamak”, respectively.
We are also proud for having invited two lecturers. First, Vincenzo Amendola, an associate professor of physical chemistry in the Department of Chemical Sciences of Padova University (Italy) gave a plenary talk on the “Laser assisted synthesis of magneto-plasmonic and UV-vis-NIR plasmonic nanoparticles”. Next, Andrei Pipa, research associate at the Leibniz Institute for Plasma Science and Technology (Greifswald, Germany) held the talk on the “Equivalent circuit approach for electrical diagnostics of dielectric barrier discharges”. We would like to use this opportunity to thank them for coming.

Branimir Blagojević, our former member, is again collaborating with us. Namely with Ivke’s and Prof. Konjević’. Together they published the article on “Semiclassical calculations of stark broadening parameters of He I lines, revisited” in Journal of Quantitative Spectroscopy and Radiative Transfer.
We are happy to announce that Biljana’s article on “Novel plasma source for safe beryllium spectral line studies in the presence of beryllium dust” has been published in Review of Scientific Instruments. We are even more proud that the article was chosen for the AIP Editor Pick’s collection. Note that the significant contribution of co-authors should not overseen.
We are honored to announce that Journal Spectrochimica Acta B just published two articles to tribute long-lasting and fruitful scientific career of Prof. Konjević: “Tribute to Nikola Konjević” and “Nikola Konjević and the Belgrade School of Spectroscopy: 50 Years of Scientific Leadership and Contributions to the Advancement of Plasma Diagnostics”.
These publications are result of Symposium “Diagnostics of low-temperature plasma and gas discharges” (2015) organized by dr Kuraica and dr Ivković (both PhD students and collaborators of Prof. Konjević) to honor 50 years of scientific work and 75th birthday.
Ivke visited the Extreme Light Infrastructure (ELI) in Bucharest with colleagues from Physical Faculty (Belgrade). The visit was realized as part of the project “Laser induced plasmas: Spectroscopic diagnosis and applications in photonic and bio nanotechnologies” through the Romanian Academy of Sciences. The visit was realized from 3rd to 7th October 2016.
