The conference was organized by the Stefan Meyer Institute for Subatomic Physics and hosted by the University of Applied Arts. Compared to previous editions of the conference, which encompassed a wider range of topics, including dark matter and cosmology, the scientific program for SSP2022 concentrated more on fundamental symmetries and interactions in both theory and laboratory experiments, as proposed by the International Advisory Committee. The conference welcomed 74 attendees who presented 51 invited and contributed talks showcasing scientific accomplishments from around the world. These included topics on searches for lepton flavor violation and symmetries in heavy quark decays at BELLE in Japan, BESIII in Beijing, muon decay at the Paul Scherrer Institute (PSI), and Φ decays at DAΦNE in Frascati. Prospects to discover physics beyond the Standard Model, such as the g-2 measurement at Fermilab, or in high energies colliders, were also presented, as well as searches for the electric dipole moments (EDM) of the neutron, deuteron, muon, and in atoms and molecules. Double ß-decay, sterile neutrino searches, and flavor oscillations were also discussed. Results and upper limits on CPT tests with antihydrogen, muonium, and positronium were reported. The meeting ended with presentations on advanced instrumentation and on upcoming future facilities at PSI, Deutsches ElektronenSynchrotron, Mainz University, and the Japan Proton Accelerator Research Complex. The reduced in-person participation from regions such as China was overcome by two remote talks that were received with the same amount of attention and interest. The proceedings have been published in the EPJ Web of Conferences. Fruitful discussions on various physics subjects thrived during the poster session, where 17 posters were presented by master’s and Ph.D. students on their work and results. Several referees had the task of evaluating each poster, and two prizes sponsored by Nuclear Physics European Collaboration Committee were awarded at a ceremony to Alexander Boeschoten from Van Swinderen Institute in Groningen for the poster “Understanding of Systematic Effects in eEDM Searches with Diatomic Molecules” and Marlene Tüchler from the Stefan Meyer Institute for the poster “Kaonic Atom X-Ray Spectrocopy with the SIDDHARTA-2 Experiment”. The social program included a guided tour at the Museum of Applied Arts in Vienna and a reception. A public lecture took place in the picturesque Festsaal of the Austrian Academy of Sciences as part of the SSP2022 program. The talk, entitled “The Underground World of Elementary Particles,” was given in German by Prof. Stefan Paul from the Technical University of Munich (Figure 1).

However, these data are often subject to significant uncertainties or simply not available. The reason is the difficulty to produce samples containing the radioactive nuclei of interest. Neutron-induced reactions are also very difficult to describe theoretically, mainly because we are not able to predict accurately how the nucleus deexcites (i.e., how it releases the internal energy acquired after the capture of a neutron). The excited nucleus may decay by the emission of γ rays, the emission of a neutron, or by fission, if the excited nucleus is heavy enough. These three deexcitation modes compete with each other and have different probabilities. The latter probabilities depend on fundamental properties of the nucleus, such as nuclear-level densities, γ and particle transmission coefficients, or fission barriers, which are very difficult to calculate if experimental data are not available. Nuclear rEaCTions At storage Rings (NECTAR) aims to circumvent these problems by using the surrogate reaction method in inverse kinematics. In standard measurements in direct kinematics, a beam of neutrons interacts with a heavy, radioactive nucleus at rest. In NECTAR, the kinematics of the nuclear reaction are inverted and the heavy, unstable nucleus is put in the beam to bombard a light nucleus. Because free neutron targets are not available, we use targets of light nuclei such as protons or deuterons. By appropriately choosing the projectile nucleus we can produce the excited nucleus that is formed in the neutron-induced reaction of interest with inelastic-scattering or transfer reactions. The probabilities as a function of the nucleus excitation energy for the different deexcitation modes, which can be measured with the alternative or surrogate reaction, are particularly useful to constrain the models describing the fundamental nuclear properties mentioned above and eventually lead to much more accurate theoretical predictions for neutron-induced reactions [1]. Figure 1 shows the idea behind the surrogate-reaction method. The use of inverse kinematics makes it possible to study very unstable nuclei by using radioactive ion beams. It also makes possible the detection of the heavy products of the decay of the excited nucleus. This simplifies significantly the determination of the γ and neutron emission probabilities because the detection efficiencies for the heavy products can be much larger than the detection efficiencies for γ rays or neutrons. However, the deexcitation probabilities change very rapidly with excitation energy at the particle and at the fission thresholds. The excitation-energy resolution required to scan this rapid evolution is a few 100 keV, which is quite difficult to achieve for heavy nuclei in inverse kinematics due to long-standing target issues. Indeed, to infer the excitation e","PeriodicalId":38978,"journal":{"name":"Nuclear Physics News","volume":"9 1","pages":"19 - 22"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89803030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
