【 摘 要 】

We have experimentally investigated dissociative recombination of NH+with electrons using a merged ion and electron beam configuration in a storage ring. A fast counting and position sensitive imaging detector enabled us to perform fragment imaging measurements over relative electron-ion collision energies from 0 to 12 eV. The results show unprecedented details on product excitation and on the reaction dynamics.
