Abstract To better understand the propensity for the three-body breakup in dissociative recombination (DR) of dihydrides (H{sub 3}{sup +} , NH{sub 2}{sup +} , CH{sub 2}{sup +} , and H{sub 2}O {sup +} ), we undertook a study of the dynamics of this process. A study of DR of H{sub 2}O {sup +} to give O+H+H was carried out at the CRYRING Heavy-Ion Storage Ring in Stockholm. With the stored beam energy of 4.5MeV, we separated the O signal from the H signals with a differential absorber, thus reducing the problem to a sum of two two-body problems. Results included (1) the ratio of O({sup 3} P) to O({sup 1} D) product, (2) the distribution of recoil-kinetic energy between the two hydrogen atoms, (3) the angular distribution between the hydrogen atoms in the O({sup 3} P) channel and in the O({sup 1} D) channel.
