摘要
对γ射线辐照的较大浓度ＡｇＮＯ３水溶液中的吸收光谱进行了研究，观察到寿命长达１个月以上的银原子团簇。讨论了实验条件对银原子团簇和胶体银的形成和稳定性的影响。
Abstract The long-lived silver cluster has been detered in γ- irredintal concentrsted AgNO3 solutions. The cluster survives for more than one month at room temiperature in air. The influences of experimental parameters on the formation and stability of the silver cluster and colloidel silver are discussed
