International Workshop on Dissociative Electron Attachment

The 2^nd International Workshop on Dissociative Electron Attachment (DEA) would be held at the Tata Institute of Fundamental Research, Mumbai, India, during 18-20 Nov. 2015. This will be the second meeting of the DEA Club, the first of which was the International Workshop held at ICTP Trieste during 16-19 Sept 2013.  The occasion will also coincide with the completion of 10 years of using momentum imaging in DEA studies. The meeting is expected to cover all aspects of DEA, related areas and its applications.

Dissociative electron attachment, which follows the resonant capture of electron by a molecule, is the dominant inelastic process in low energy electron-molecule collisions. Resonant electron attachment is the most efficient way of transferring the kinetic energy in a medium to the chemical energy in the form of vibrational and electronic excitation, and production of radicals and negative ions. All these excited species and radicals are highly reactive and they form the basis of all subsequent chemical reactions in the medium. Thus collision of electrons plays a major role in atmospheric chemistry, astrochemistry, plasma physics and chemistry, nanolithography, dielectric aging, radiation waste management, pollution control, photochemistry at surfaces and radiation damage and therapy. Recent experiments have shown that dissociative attachment of low energy electrons to molecules can be used as a tool to control electron induced chemistry. However, in order to exploit DEA to its full potential and apply it to specific technological applications, it is necessary to study this process in detail defining both the internal energy distribution of the fragments and the dynamics of the fragmentation process. It was in this context, that a novel ion momentum imaging technique specifically suited to low energy electron-molecule collisions was designed and developed at TIFR. After the first publication of this technique in 2005, several similar experiments have been built across the world, providing several new insights into the complex phenomenon of DEA. This Workshop would help in assessing these techniques and provide a platform for international collaboration in this area. In addition, the meeting would address several other aspects of DEA and its applications. This would include, electron induced chemistry on surfaces, role of electron as a catalyst, electron-induced processes in plasmas, low energy electrons in radiation damage and therapy, application to nanolithography, astrochemistry and single molecule engineering using STMs.
