Electron stimulated desorption techniques were applied to probe the density of H-2 physisorbed on a cold surface. The adsorption isotherm of H-2 on a copper surface was measured in the equilibrium pressure range between 10(-9) and 10(-4) Pa at sur...
Triboluminescence spectra were measured by means of pin-on-disk method for several samples of natural diamond and a synthetic quartz disk in Ne or N2 gas at pressures between 10 and 105 Pa. At the gas pressure bet...

To understand physico-chemical processes at real contacts (asperities) on fault surfaces, we conducted pin-on-disk friction experiments at room temperature, using single crystalline quartz disks and quartz pins. Velocity weakening from friction co...

Photo-stimulated desorption of ions from methane and water heteroclusters on the surface of solid neon was studied. The desorption yields of various photo-desorbed species showed strong dependence on the composition and size of the mother cluster....
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...
