| Outline of Final Research Achievements |
A molecular collision apparatus which controls internal degrees of freedoms of reactants as well as the translational energy has been built. Merging-beam experiments for ion-molecule reactions were carried out. Quantum effects on the reactivity, which was expected under a low collision energy condition, was not observed. We localized the technical problem; the slow ions with too high concentration generated with a focused laser beam significantly loose the intensity. An ion-imaging detector was introduced to obtain high sensitivity for a low concentration ion beam, whose translational energy resolution is kept narrow. We organized the collaboration to have technical supports for the slow ion control. In the collaboration, we measured the high-resolution spectra of O2H+ and CH3+ ions with an ultracold trap, which utilizes the same deceleration device as that with the developed apparatus. The spectral analysis yielded characteristic interactions in ion chemistry.
