在离子储存环中首次测量了能量在0.3 ~ 40 eV之间的HD ^{+}$分子与电子的解离复合截面。离子束，存储的平均寿命为\ensuremath{\sim}5秒，被观察到振动冷。在测量的截面中，出现了理论预测的高能共振，这可以归因于通过HD的双激发里德堡态的复合。
The dissociative recombination cross section between ${\mathrm{HD}}^{+}$ 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 \ensuremath{\sim}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.
