摘要
Thermally stimulated exoelectron emissions (TSEE) from nickel and oxidized nickel surfaces after excitation by means of abrasion and X-ray irradiation in air were measured using a gas-flow type G-M counter equipped with the heating unit. There were three remarkable peaks in the TSEE glow curves up to 400 degree C; at about 120 degree C (1st), 230 degree C (2nd) and 350 degree C (3rd). The emission intensity was stronger in the samples excited by X-ray irradiation than in those excited by abrasion. Oxidized nickel and nickel oxide powder without excitation showed the third peaks only.
