Title: Resonant ion-pair formation in electron collisions with rovibrationally cold H{sub 3}{sup +}

Journal Article · · Physical Review. A

Experimental and theoretical cross sections for the resonant ion-pair formation (RIP) in electron collisions with rovibrationally cold H{sub 3}{sup +} ions are presented. Absolute cross sections for the RIP process producing H{sup -} 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 H{sub 3}{sup +} and H{sub 3}.
