Only the A\u2032-resonance contribution, describing the near-threshold behavior of DEA, is incorporated. Calculations are based on the nonlocal complex potential theory and the multiple scattering theory, and are performed for a model target with basic properties of uracil and thymine, surrounded by five water molecules. The DEA cross section is strongly enhanced when the attaching molecule is embedded in a water cluster. This growth is due to two effects: the increase of the resonance lifetime and the negative shift in the resonance position due to interaction of the intermediate negative ion with the surrounding water molecules. A similar effect was earlier found in DEA to chlorofluorocarbons.<\/jats:p>","DOI":"10.1063\/1.4874841","type":"journal-article","created":{"date-parts":[[2014,5,13]],"date-time":"2014-05-13T00:30:30Z","timestamp":1399941030000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":51,"title":["Electron-induced hydrogen loss in uracil in a water cluster environment"],"prefix":"10.1063","volume":"140","author":[{"given":"M.","family":"Smyth","sequence":"first","affiliation":[{"name":"Queen's University Belfast 1 Atomistic Simulation Centre, , Belfast BT7 1NN, Northern Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Kohanoff","sequence":"additional","affiliation":[{"name":"Queen's University Belfast 1 Atomistic Simulation Centre, , Belfast BT7 1NN, Northern Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.
