Resonant multi-photon ionization was employed to create the charged reactant Ar+ in the 2P3\/2 spin\u2013orbit ground state with high purity. At the lowest studied collision energy of 40\u00a0meV, we could observe the N2+ product in the v = 0 vibrational level with a high amount of rotational excitation. This level is strongly dynamically suppressed at higher collision energies, where excited vibrational levels become accessible. In addition, a higher fraction of backward scattering is observed at this low collision energy compared to higher collision energies. This shows that the reaction dynamics of the charge-transfer reaction undergo a profound change from direct to unusual complex-mediated charge transfer dynamics at very low collision energy.<\/jats:p>","DOI":"10.1063\/5.0322634","type":"journal-article","created":{"date-parts":[[2026,3,23]],"date-time":"2026-03-23T12:21:56Z","timestamp":1774268516000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["Charge transfer dynamics of the Ar+(2P3\/2) + N2 reaction at very low collision energies"],"prefix":"10.1063","volume":"164","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-8489-4668","authenticated-orcid":false,"given":"Dasarath","family":"Swaraj","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Ionenphysik und Angewandte Physik, Universit\u00e4t Innsbruck , Technikerstra\u00dfe 25, 6020 Innsbruck,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-4107-2446","authenticated-orcid":false,"given":"Jerin","family":"Judy","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Ionenphysik und Angewandte Physik, Universit\u00e4t Innsbruck , Technikerstra\u00dfe 25, 6020 Innsbruck,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4452-8520","authenticated-orcid":false,"given":"Fabio","family":"Zappa","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Ionenphysik und Angewandte Physik, Universit\u00e4t Innsbruck , Technikerstra\u00dfe 25, 6020 Innsbruck,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2808-2760","authenticated-orcid":false,"given":"Viviane C.","family":"Schmidt","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Ionenphysik und Angewandte Physik, Universit\u00e4t Innsbruck , Technikerstra\u00dfe 25, 6020 Innsbruck,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7935-6066","authenticated-orcid":false,"given":"Roland","family":"Wester","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Ionenphysik und Angewandte Physik, Universit\u00e4t Innsbruck , Technikerstra\u00dfe 25, 6020 Innsbruck,","place":["Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,3,23]]},"reference":[{"key":"2026032308215439500_c1","doi-asserted-by":"publisher","first-page":"2319","DOI":"10.1103\/physreva.23.2319","volume":"23","year":"1981","journal-title":"Phys.
