一、引言六十年代初,荷兰原子分子研究所的J.Kistemaker,C.Snoek和W.F.Van der Weg利用由同位素分离器得到的60keV的氩离子,15keV的氩离子和氖离子轰击铜靶,观察到从铜辐射出来的CuⅠ和CuⅡ谱线。同时,他们还对氧化亚铜进行了研究,氧化亚铜的光子产额比铜的光子产额要高得多。以后,又经过许多人的努力,终于在1971年由C.W. I. INTRODUCTION In the early 1960s, J.Kistemaker, C.Snoek, and WF Van der Weg, Institute of Atomic and Molecular Sciences, Netherlands, used a 60keV argon ion obtained from an isotope separator to bombard copper targets with 15keV argon ions and neon ions To Cu I and Cu II lines that radiate from the copper. At the same time, they also studied cuprous oxide, which produced much higher photon yields than copper. Later, after many people’s efforts, finally in 1971 by C.W.
