This paper reviews our progress on the desorption induced by electronic transitions ( DIET) in rare gas solids by selective excitation of valence excitons. Observation of metastable atoms desorbed by excitonic excitation gives us direct informatio...

To clarify the fractal natures of electromagnetic radiations prior to earthquakes, we conducted a friction experiment simulating the essential elements of the motion of an asperity on a fault plane, and observed the generation of photon emissions ...
Adsorption isobars of Xe and Kr oil Ag(111) and Ag(100) Nvere observed Simultaneously by an extremely-low-current low energy electron diffraction and an ellipsometry in the temperature range between 60 K and 90 K and in the equilibrium pressure ra...

By a pin-on-disk frictional experiment simulating the motion of an asperity on a fault plane, we observed photon emissions from the gap between the quartz disk and pins made of natural semiconductor or insulator minerals during friction. The patte...
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...
