摘要：

The dissociative recombination cross section between HD+ molecules and electrons at energies between 0.3 and 40 eV has been measured for the first time in an ion storage ring. The ion beam, stored with a mean lifetime of approximately 5 s, was observed to be vibrationally cold. In the measured cross section, theoretically predicted high-energy resonances appeared. Which can be attributed to recombination via doubly excited Rydberg states of HD.
