Resonant ion-pair formation from the collisions of NO+ ions with electrons was studied using the heavy-ion storage ring CRYRING at the Manne Siegbahn Laboratory of Stockholm University. The total cross section is measured for the formation of N+ +Ofor electron energies 8–18 eV, and the results are compared with ion-pair formation in photoionization work. A peak in the cross section is observed at 12.5 eV, with a magnitude of 8.5×10–19 cm2. An attempt to extract the cross section for the reverse process of associative ionization is made.
