Research Interest:
We are studying low-energy (<15eV) electron collisions with molecules in gas phase forming electron-molecule
resonances. The negative excited ion thus formed (called the Temporary Negative Ion) dissociates into fragments of
neutrals and ions. This process is called the Dissociative Electron Attachment (DEA). We then study the DEA ion-
yield curve, kinetic energy of fragment ions and angular distribution. Electron-molecule collision at higher energy is
also studied where the electron gets scattered by the molecule and transfers some of its energy to the molecule. The
later then breaks into cation and anion. This process is called Polar Dissociation.
Present work:
A supersonic gas jet is generated by cooling down a gas and expanding it during which the specific enthalpy is
converted into kinetic energy respecting energy conservation. The ultra-cold supersonic gas target is formed when
high-pressure gas passes through a small aperture (nozzle) into a region of low pressure where it expands quasi-
statically and adiabatically. The inclusion of a gas jet, as opposed to an effusive gas beam, allows for the target with
low initial vibrational and rotational energy, which is also confined spatially. An Amsterdam Cantilever Peizo Valve
(ACPV) is installed in a custom designed jet expansion chamber. The ACPV is tested and brought to working
condition. Experiments are going on to optimize the set-up for Oxygen and perform supersonic gas jet and electron
collisions for various molecules.
