Formation of Hydroxyl Anion via a 2-Particle 1-Hole Feshbach Resonance in DEA to 2-Propanol: A Joint Experimental and Theoretical Study
Siddique Ali, Meeneskhi Rana, Soumya Ghosh +3
Absolute cross sections for the formation of OH- from 2-propanol (CH3CH(OH)CH3) via dissociative electron attachment (DEA) are reported in the incident electron energy range of 3.5…

Electron Impact Fragmentation Dynamics of Carbonyl Sulfide: A Combined Experimental and Theoretical Study
Soumya Ghosh, Narayan Kundu, Aryya Ghosh +1
In this study, we examine the interactions of low- to intermediate-energy electrons (045 eV) with carbonyl sulfide (OCS). These collisions lead to the formation of several anion…

Observation of Resonant Tunneling from Molecular Shape into Vibronic Feshbach Resonances Followed by Mode-Specific Fragmentation
Narayan Kundu, Meenakshi Rana, Aryya Ghosh +1
We present a kinematically complete study of dissociative electron attachment (DEA) in linear OCS molecules, focusing on how electrons resonantly attach and trigger dissociation. N…
