We present calculated cross sections for dissociative recombination of the He{sub 2}{sup +} molecular ion in the 1 to 15 eV energy region, where the cross section is dominated by a series of resonances, the repulsive Rydberg states converging to the first excited state of the ion. The resonance parameters for this system were obtained from electron scattering calculations using the complex Kohn variational method. The dissociation dynamics were studied using a time-dependent wave packet calculation. The calculated cross section is reported and compared to available experiment. The effects of rotation and vibration on the total cross section is examined, as well as the effect of electronic couplings on the final state distribution.
