Orbital pattern imaging

分子的特性是由它们的波函数决定的。通过对经弹性散射的电子和电离的电子产生的同样的能量和动力的共同测量，有可能确定目标分子的选定轨道的波函数。这一技术被称为“电子动力光谱”，而且已经开发得如此之远，在澳大利亚，美国。和加拿大。作为信号如此弱、如此高、如此高、两者分辨率和S/N比率对于定量分析都是不充分的。这个项目是以一个更有效的开发为目标的，作为一个高分辨率设备，A2-dimensional Detector已被收购，并协同检测电子和电子资源已被构建为一个现有赠款，并用一个腔室组装成一个涡轮分子泵制造设备。总系统的规格已被他确认，关于哪个波功能实际上是确定的，因此HOMO的功能形式是如此之远（Glyoxal的最高占用分子轨道）（C型D22型D22型D2 O型D22型D22型D2） molecule has been studed with this system， and preliminary results have been sent to an international conference（原子、分子和表面的多粒子光谱学）我们将在今年夏天在德国哈勒被抓住。

Properties of molecules are determined by their wave function. By coincident measurements of energy and momentum of the inelastically scattered electron and the ionized electron produced simultaneously, it is possible to determine the wave function of a selected orbital of the target molecule. This technique is called "electron momentum spectroscopy" and has been developed so far by several groups in Australia, U.S.A., and Canada. Being the signals so weak, however, both resolution and S/N ratio are insufficient for quantitative analysis. This project has aimed at a development of a more efficient as well as high-resolution apparatus.A 2-dimensional detector has been purchased, and coincidence detection electronics and electron sources have been constructed with the present grant in aid together with a chamber equipped with a turbomolecular pump to make the apparatus. The specification of the total system has been confirmed with He, about which wave functions have been accurately determined.So far functional forms of HOMO (highest occupied molecular orbital) of glyoxal (CィイD22ィエD2HィイD22ィエD2OィイD22ィエD2) molecule has been studied with this system, and preliminary results have been sent to an international conference (Many-Particle Spectroscopy of Atoms, Molecules and Surfaces) which is going to be held at Halle, Germany, this summer.
