Już 5 marca 2026 roku o godz. 12:30 w Audytorium Aleksandra Jabłońskiego prof. dr. Edvardas Narevicius (Technical University Dortmund, Niemcy) wygłosi wykład pt. "Probing Quantum Scattering Resonances in Ion–Neutral Interactions via Rydberg Collisions".
Streszczenie:
We present recent experimental results on the observation of quantum scattering resonances in ion–neutral collisions at cold and ultracold interaction energies. Accessing this regime with ions is inherently challenging due to excess micromotion energy in ion traps; we overcome this limitation by employing Rydberg states, in which the highly excited electron acts as a spectator, effectively decoupling the ionic core from the trapping fields. This approach allows us to reach the cold collision regime and resolve shape resonances in both elastic scattering and charge exchange reactions. Our results open a new window into the quantum mechanical nature of ion–neutral interactions and lay the groundwork for controlled chemistry at the quantum limit.
