Electron-Impact Quasi-Resonant Ion-Pair Dissociation of OCS: A Velocity Slice Imaging Study with Partial Wave Analysis
Narayan Kundu, Soumya Ghosh, Dhananjay Nandi
We present velocity map imaging data on intramolecular ion-pair dissociation (IPD) of carbonyl sulfide (OCS) induced by electron impact over the 20 eV to 45 eV energy range. Two di…
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…
Study of low-energy electron-induced dissociation of 1-Propanol
Soumya Ghosh, Dipayan Chakraborty, Anirban Paul +1
The fragmentation of 1-propanol resulting from dissociative electron attachment has been explored across an energy range of 3.5 to 16 eV. Four distinct ion species are identified:…
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…
