Controlling the Spin-Orbit Branching Fraction in Molecular Collisions

Cornelia G. Heid et al.

Summary: This research demonstrates how the initial orientation of NO molecules relative to approaching Ar atoms determines the branching between the spin-orbit changing and the spin-orbit conserving rotational product channels. Tuning the initial collision geometry can achieve a substantial control over the final spin-orbit state of the scattering products.

Determining the nature of quantum resonances by probing elastic and reactive scattering in cold collisions

Prerna Paliwal et al.

Summary: Scattering resonances play a central role in collision processes, providing intuitive understanding of collision dynamics. Resonances localized in the reaction region lead to sharp peaks in reaction rates, while those outside the reaction region mainly modify elastic scattering.

Quantum interference between spin-orbit split partial waves in the F plus HD → HF plus D reaction

Wentao Chen et al.

Summary: The study investigates the impact of electron spin-orbit interactions on the F + HD -> HF + D reaction using a combination of experimental observations and theoretical analysis. The researchers observed a peculiar horseshoe-shaped pattern in the product rotational-state-resolved differential cross sections, which could only be explained accurately when full spin-orbit characteristics were considered. Theoretical analysis revealed that the unusual dynamics pattern was largely due to quantum interference between spin-orbit split-partial-wave resonances with positive and negative parities, showcasing how spin-orbit interaction can effectively influence reaction dynamics.

Monitoring atmospheric 85Kr by atom counting

Chao Gao et al.

Summary: The study introduces an ultra-sensitive method for fast analysis of atmospheric Kr-85 at the parts per trillion level, based on laser cooling and trapping technology. This method allows for accurate measurements of krypton extracted from 1L STP of air in a short time frame, laying the groundwork for establishing a global atmospheric Kr-85 monitoring network.
