摘要
应用高分辨库仑爆炸技术,测量了氘化星际分子H_2D^+的库仑爆炸产物能谱。实验结果证明H_2D^+是等腰三0 形结构;它的核间距R_(HH)=l.33±0.12(?),R_(HD)=0.95±0.06(?)和束缚能ε=41.2±3.0eV。
The energy spectrum of the Coulomb explosion products of H2D+, a interstellar molecular, is measured by high resolution Coulomb explosion technique. The results of this experiment demonstrate that H2D+ has a structure of triangle. By the way, the separations between its nuclei are decided as RHH = 1. 33 ± 0. 12 A and RHD =0. 95±0. 06 A and its bound energy is also deduced as e = 41. 2±3. 0 eV for the first time, respectively.
