Latvijas Council of Science project on Fundamental and Applied Sciences No. lzp-2023/1-0199 "The Laser Photodetachment Spectroscopy on Negative Ions" was approved for funding. The Leader of the project - ERA Chair team member Dr. Uldis Berzins.
Abstract of the project proposal: During the project, studies of the structure and dynamics of negative ions will be performed with the aim of improving our knowledge and understanding of atomic systems in which electron correlation effects play a major role. Spectroscopic measurements of the process of removing an electron from negative ions will be studied. Several experimental equipment will be used for the work. Initial experiments will be carried out on the ion beam equipment GRIBA (Gothenburg Riga Ion Beam Accelerator), which is located at the Institute of Atomic Physics and Spectroscopy, using the TOF (Time of Flight) spectrometer. Information on the structure of negative ion energy levels will be obtained. The obtained information will make it possible to plan the scheme of the experiment and the necessary (mainly lasers) for high-precision measurements on very advanced experimental equipment at Europe's leading science facilities: GANDALPH at CERN, and DESIREE at Stockholm University. Finally, high-precision data will be obtained and will be published in the world's leading journals and reported at conferences. Senior scientists will work on the project together with MSc, BSc and PhD students. Their results will be used in their PhD, master and bachelor thesis. The data for negative ions are needed by specialists in various fields of science and technology: atomic and molecular physics, nuclear physics, astrophysics, atmospheric photochemistry, medicine, semiconductor industry, energetics etc.
