Recent research results on translational kinetic energy effects of incident oxygen molecules for Si(001) oxidation are summalized and introduced. The variation of surface temperature dependence of SiO desorption yield, oxygen uptake curves, and chemical bonding states depending on translational kinetic energy of oxygen molecules is described concretely. Eapecially, the translational kinetic energy effects on chemical reaction processes of concurrent oxide-layers formation and SiO desorption are discussed.

Irradiation assisted stress corrosion cracking (IASCC) is a degradation phenomenon caused by synergy of neutron radiation, aqueous environment and stress on in-core materials, and it is an important issue in accordance with increase of aged light water reactors. Isolating crack initiation stage from crack growth stage is very useful for the evaluation of the IASCC behavior. Hence facility for in-situ observation during slow strain rate test (SSRT) for irradiated material was developed. As performance demonstrations of the facility, tensile test with in-situ observation and SSRT without observation were carried out using unirradiated type 304 stainless steel in 561 K water at 9 MPa. The following were confirmed from the results. (1) Handling, observation and recording of specimen can be operated using manipulators in the hot cell. (2) In-situ observation can be performed in pressurized high temperature water and flat sheet type specimen is suitable for the in-situ observation. (3) Test condition can be kept constantly and data can be obtained automatically for long test period.

Real-time in-situ photoemission spectroscopic studies on Ti(0001) oxidation by O
molecules at 473K-673K are reviewed. The Ti(0001) surface was changed from metal to oxide during exposure to oxygen gas. From the time dependent Ti-2p photoemission spectra, time evolution of each oxide component of Ti was clarified.
