Dissociative electron attachment and dipolar dissociation in ethylene

- In DEA and as well in DD to ethylene H−, C−, CH−, CH2−, C2−, C2H−, C2H2− and C2H3− anions are observed.
- Newly observed anions for ethylene are: C− and C2H2−.
- The present calculations of thermochemical thresholds indicate that for several resonances formation of stable neutral molecules from released fragments occurs which lowers the threshold of the DEA reaction.
