In the present research, new electron spectroscopic techniques have been developed for verious molecular systems including clusters ; (1) Collision Energy Resolved Penning Ionization Electron Spectroscopy (CERPIES), (2) measurements for Collision Energy Dependence of Partial Penning Ionization Cross Sections (CEDPICS), (3) Two-Dimensional Penning Ionization Electron Spectroscopy (2D-PIES), (4) Time-Correlation Penning Ionzation Electron Spectroscopy (TCPIES), and (5) Laser-Desorption Penning Ionization Electron Spectroscopy (LDPIES). In the last year of the term of the project, 2DPIES,TCPIES,and LDPIES were developed.The 2DPIES system including an order-made electronic system was constructed and the observation of 2DPIES was made for the first time.The TCPIES technique using a cross-correration time-of-flight method was developed. Sensitivity of signal detection for velocity resolved Penning electron spectroscopy was improved by a factor of ca.10-30.The LDPIES method was developed for observing PIES of low-volatile samples of little amount in a short time without thermal decomposition.

在目前的研究中，新的电子能谱技术已经开发用于包括簇在内的各种分子系统； (1) 碰撞能量分辨潘宁电离电子能谱 (CERPIES)，(2) 部分潘宁电离截面碰撞能量依赖性的测量 (CEDPICS)，(3) 二维潘宁电离电子能谱 (2D-PIES)，(4) ) 时间相关彭宁电离电子能谱 (TCPIES)，以及 (5) 激光解吸彭宁电离电子能谱 (LDPIES)。在项目期限的最后一年，开发了2DPIES、TCPIES和LDPIES。构建了包括定制电子系统的2DPIES系统，并首次对2DPIES进行了观测。TCPIES技术使用交叉- 开发了相关飞行时间方法。速度分辨潘宁电子能谱的信号检测灵敏度提高了约10-30倍。LDPIES方法是为在短时间内观察少量低挥发性样品而不发生热分解而开发的。
