| 摘 要： | The bond length of ^4HeH^＋ resulting from collision-induced destruction is measured at 1.4420 MeV using the Coulomb Explosion Technique. The measured bond length of ^4HeH^＋ is 0.094±0.003nm. The bond length of ^4HeH^＋ obtained with our radio frequency （RF） ion source is larger than that obtained with a duoplasmatron ion source at Argonne National Laboratory （ANL）, but the bond lengths of H^＋2 and H^＋3obtained separately by ANL and by us with the two different ion sources are consistent with each other, which implies that there exists an ion source effect on the bond length of ^4HeH^＋. The main reason why the 4^4HeH^＋ bond lengths obtained by the two different ion sources are different is also discussed.

| Abstract: | The bond length of ^{4}HeH^{+} resulting from collision-induced
destruction is measured at 1.4420 MeV using the Coulomb Explosion
Technique. The measured bond length of ^4HeH^+ is 0.094\pm 0.003nm. The
bond length of ^{4}HeH^{+} obtained with our radio frequency (RF) ion
source is larger than that obtained with a duoplasmatron ion source at
Argonne National Laboratory (ANL), but the bond lengths of H_{2}^{+}
and H_{3}^{+}obtained separately by ANL and by us with the two
different ion sources are consistent with each other, which implies that
there exists an ion source effect on the bond length of ^{4}HeH^{+}.
The main reason why the ^{4}HeH^{+} bond lengths obtained by the two
different ion sources are different is also discussed. |
