【摘要】 北京正负电子对撞机(BEPC)提供同步辐射(SR)白光做激发源,束斑尺寸50μm×50μm,计数时间20s,位移200μm/步,扫描测量石榴石中元素(Fe,Mn,Ca)分布.得到清晰的元素分布图。更多还原

【Abstract】 A piece of garnet mononineral was scanned for its elemental distribution by using a 50μM ×50μm white SR beam which was provided by BEPC as excination source. The analytical con-ditions were as follows: 20 s counting time, 200μm/step, solid state Si(Li) detector and airpath. Obvious annular distribution of Fe, Ca and Mn were obtained.更多还原
