We report first results obtained during the commissioning of Laser Resonance Chromatography (LRC) apparatus, which is conceived to enable atomic structure investigations in region heaviest elements beyond nobelium. In our studies we established optimum conditions for operation different components setup, including radio-frequency quadrupole ion buncher and cryogenic drift tube, was operated with helium buffer gas at relatively low electric fields. used laser ablated hafnium, lutetium,...
The quantum-mechanical nuclear-shell structure determines the stability and limits of existence heaviest nuclides with large proton numbers Z ≳ 100 (refs.
RAdiation-Detected Resonance Ionization Spectroscopy (RADRIS) is a versatile method for highly sensitive laser spectroscopy studies of the heaviest actinides. Most these nuclides need to be produced at accelerator facilities in fusion-evaporation reactions and are studied immediately after their production separation from primary beam due short half-lives low rates only few atoms per second or less. Only recently, first spectroscopic investigation nobelium (Z=102) was performed by applying...
Research on superheavy elements enables probing the limits of nuclear existence and provides a fertile ground to advance our understanding atom’s structure. However, experimental access these atomic species is very challenging often requires development new technologies techniques optimized for study single species. The Laser Resonance Chromatography (LRC) technique was recently conceived enable structure investigations in region elements. Here, we give an update progress simulation results.
The radiation detection resonance ionization spectroscopy (RADRIS) technique enables laser spectroscopic investigations of the heaviest elements which are produced in atom-at-a-time quantities from fusion-evaporation reactions. To achieve a high efficiency, is performed buffer-gas environment used to thermalize and stop high-energy evaporation residues behind velocity filter SHIP. required cyclic measurement procedure combination with applied filament collection for neutralization as well...
Abstract Relativistic effects strongly influence the chemical and physical properties of heaviest elements, which can significantly differ from periodicity predicted by periodic table elements. Former systematic mobility measurements on monoatomic lanthanide ions revealed dependence ion-atom interactions underlying electronic configuration helped in studying aforementioned effects. Presently, are being extended to actinides, where larger deviations expected. Our studies will cover ion...

Relativistic effects strongly influence the electronic structures of heaviest elements, thereby shaping their chemical and physical properties. Studying ion mobility within a noble gas environment reveals how ion-neutral interactions depend on ion's configurations, thus providing an avenue for exploring these effects. An spectrometer with cryogenic drift tube was developed to precisely measure low-field reduced heavy lanthanide actinide cations. The apparatus characterized by optimizing...
The beam-helicity asymmetry was measured, for the first time, in photoproduction of $\pi^{0}\eta$ pairs on carbon, aluminum, and lead, with A2 experimental setup at MAMI. results are compared to an earlier measurement a free proton corresponding theoretical calculations. Mainz model is used predict nuclear targets. present indicate that mechanism nuclei similar nucleon. This process dominated by $D_{33}$ partial wave $\eta\Delta(1232)$ intermediate state.
