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,...
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...
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...
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...
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...
