  1. 78. Atomic physics with stored HCIs
    Thomas STOEHLKER (HI Jena and GSI Helmholtzzentrum für Schwerionenforschung)
    20/11/2024, 08:30
    Invited talk

    At GSI and FAIR, atomic physics with stored HCIs is the focus point of the international SPARC collaboration (Stored Particle Atomic physics Research), aiming to exploit the unrivaled combination of storage and trapping facilities, a unique feature that distinguishes FAIR from all planned or operating particle accelerators worldwide [1,2]. These facilities are unique to provide highly intense,...

  2. 41. Atomic reactions and internal targets at CSRe and HIAF
    Shaofeng ZHANG (Institute of Modern Physics, Chinese Academy of Sciences)

    Invited talk

    The study of relativistic collisions between highly charged ions and atomic or molecular targets offers a profound insight into the dynamics of correlated few-body quantum systems under the influence of intense electromagnetic fields. These interactions are characterized by complex multi-electron dynamics, where understanding electron correlations is essential. Although quantum electrodynamics...

  3. 47. Collinear laser spectroscopy program in China
    Prof. Xiaofei YANG (Peking University)
    20/11/2024, 09:40
    Invited talk

    Collinear laser spectroscopy is a powerful tool for studying fundamental properties of atomic nuclei, such as nuclear spins, magnetic moments, electric quadrupole moments, and charge radii[1]. To investigate these properties in unstable nuclei at the Radioactive Ion-beam Facility in China, we have developed a collinear resonance ionization spectroscopy system. The first phase of the setup was...

  4. 7. How to observe vacuum decay in low-energy heavy-ion collisions
    Vladimir SHABAEV (St. Petersburg State University)

    Invited talk

    It is known that in slow collisions of two bare nuclei with the total charge number exceeding the critical value, Z_1+Z_2 > Z_c =173, the initially neutral vacuum can spontaneously decay into a charged vacuum and two positrons. The detection of spontaneous emission of positrons would be a direct proof of this fundamental phenomenon. However, the spontaneous emission of positrons is usually...

  5. 32. Dielectronic Recombination studies at the CSR
    Zhongkui HUANG (Institute of Modern Physics, Chinese Academy of Sciences)
    20/11/2024, 11:10

    Dielectronic recombination (DR) is one of the dominant electron-ion recombination mechanisms for most highly charged ions (HCIs) in cosmic plasmas, and thus, it determines the charge state distribution and ionization balance therein. To reliably interpret spectra from cosmic sources and model the astrophysical plasmas, precise DR rate coefficients are required to build up an accurate...

  6. 9. Spin physics with a polarized internal target at HIAF
    Boxing GOU (IMP, CAS)
    20/11/2024, 11:30

    The High Intensity heavy-ion Accelerator Facility (HIAF) will be a major workhorse for the accelerator-based (sub)atomic physics in the multi-GeV region in the next decades. As fundamental as the mass, spin plays a profound role in the structure of microscopic particles and interactions among them. Besides, spin has long provided unique approaches to test fundamental symmetries and to search...
