A two-parameter auto-null ellipsometer system was constructed and applied for precise observation of the growth of rare gas films physisorbed on a metal surface in quasi equilibrium condition. We obtained the adsorption isobar of Xe/Ag (111) at <I...
The effect of disturbances induced by the injection of the electrons and ions from outside of the gauge on the axial-symmetric transmission gauge (AT gauge) was examined. There were less sign of disturbance in comparison to a BA gauge and an extra...
We have developed a laser-plasma vacuum ultraviolet light source (LPLS) for the purpose of using it as an excitation light source in experimental studies of Desorption Induced by Electronic Transitions (DIET). In comparison with the synchrotron li...

The growth and the structure of a Xe film physisorbed on a Ag(l 11) substrate have been investigated by means of ellipsometry and extremely low current low-energy electron diffraction (XLEED). Equilibrium between the Xe film and the coexisting thr...
We have studied electron stimulated desorption (ESD) and photon stimulated desorption (PSD) of positive ions from water absorbed on a surface of solid rare gases. In TOF spectrum, a series of ionized clusters are observed, which were thought to be...
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...
