本文对汉代一块青铜镜残片进行了~(119)Sn的穆斯堡尔谱分析。给出了透射谱与γ射线散射谱的对照,建立了一种无需取样的散射穆斯堡尔谱的测量方法。证实了该铜镜表面层锡是以Sn~4氧化物状态存在。
In this paper, we analyze the Mössbauer spectroscopy of ~ (119) Sn on a piece of bronze mirror in the Han Dynasty. A comparison of the transmission spectrum with the γ-ray scattering spectrum is given, and a measurement method of unscattered scattering Mossbauer spectroscopy is established. Confirmed that the copper surface of the tin layer is Sn ~ 4 oxide state exists.
