Help!!! Theory for H3+ recombination still needed

In spite of the great progress in theoretical and experimental studies of the dissociative recombination (DR) of H3+ in the last decade, there still remain apparent discrepancies between them. They are counted out and the effect of magnetic fields used in the storage ring experiments is considered as a possible cause of the discrepancy. In addition, the high internal temperature of H3+ revealed by experiments at the Max Planck Institute of Nuclear Physics suggests a possibility that the current value of the DR rate constant may still be off by a significant factor.
In the meantime, the importance of the DR of in the H3+ diffuse interstellar medium has grown further as astronomical observations of H3+ developed rapidly in the last decade. It has been established that H3+ is the best probe to measure intensities of low energy cosmic rays. The rate constant for the DR of H3+ is crucial in the measurement. We still desperately need the theory for the dissociative recombination of H3+!
