The photon-stimulated desorption of (H2O)(n)H+ from water physisorbed on a rare gas solid (Ne, Ar, Kr, and Xe) has been investigated. From the measurements of the desorption yield as a function of the incident photon energy, the (H2O)(n)H+ desorpt...

We measured spectra of light-emissions during sliding friction between diamond and quartz in ambient gases of He, Ne, and Ar at 10-103 Pa. Two types of the light emission were observed; one has a band spectrum specific to each gas and t...

The basic characteristics of the axial-symmetric transmission gauge (AT gauge), that were modified for measurement over a wide pressure range, are reported. A Faraday cup ion collector is used instead of a secondary electron multiplier to extend t...

We have developed a miniature cylindrical mirror analyzer (CMA) for ion kinetic energy measurements. The CMA consists of a shield for electric field, inner and outer cylinders, a pinhole, and microchannel plates. We have applied it for the measure...
低温表面上に物理吸着した水素の密度を測定するために、電子励起脱離(ESD)法を用いた。脱離したイオンを飛行時間測定法(TOF : time of flight)を用いて質量分析し、H+の収量から水素の吸着密度を決定し、その吸着等温線を求める。本研究では、広い温度範囲での吸着等温線を求めることを目的とする。また、吸着平衡に近づく過渡状態の観測から物理吸着する水素の平均滞在時間を測定する。
<p>Surface science had its beginning at the dawn of the human civilization and vacuum science in the 17th century. Collaboration between them has begun in the late 19th century and has grown in close manner in the field of sc...
