Phys. Rev. A 69, 022713 (2004) [11 pages]Resonant ion-pair formation in electron collisions with rovibrationally cold H3+Received 8 September 2003; published 26 February 2004 Experimental and theoretical cross sections for the resonant ion-pair formation (RIP) in electron collisions with rovibrationally cold H3+ ions are presented. Absolute cross sections for the RIP process producing H- ions are measured for center-of-mass energies between 2–20 eV using the CRYRING, heavy-ion storage ring. Theoretical cross sections are obtained using wave-packet propagation on both one- and two-dimensional models of relevant diabatic-potential energy surfaces and couplings of H3+ and H3. © 2004 The American Physical Society URL:
