提出了一种新的、精确的测定119锡23·875 keV激发态磁矩的方法。用Co 2 MnSn和fe3 Sn两种不同的吸收剂得到的平均值μ e=+(0.682±0.004)nm，与之前的测量结果吻合较好。建议用Heusler合金Co 2 MnSn作为119 Sn的Mössbauer速度校准标准，并给出了在4.2 K和300 K下的线位置。此外，一些其他已发表的关于57铁和119锡的核矩的数据也得到了澄清。
A new and accurate determination of the magnetic moment of the 23· 875 keV excited state of 119 Sn is presented. The mean value, μ e=+(0· 682±0· 004) nm, obtained using two different absorbers, Co 2 MnSn and Fe 3 Sn, is in good agreement with previous measurements. The Heusler alloy Co 2 MnSn is suggested as a suitable absorber to be used as a Mössbauer velocity calibration standard for 119 Sn, and the line positions are given at 4· 2 K and 300 K. In addition some of the other published data relating to the nuclear moments of both 57 Fe and 119 Sn are clarified.
