【摘要】 本文介绍一台具有多种功能的穆斯堡尔谱仪。它具有等速和等加速两种驱动方式;激光干涉测速系统可对谱仪绝对定标。等加速谱仪线性优于0. 15%(±43mm/sec 条件下测量),线宽<0. 26mm/sec(α-Fe 三、四峰)。等速谱仪线宽<0. 27 mm/sec,其稳定性在24小时内好于0. 1%。更多还原

【Abstract】 A M(?)ssbauer Spectrometer is shown in this article.It is driven with constant velocity or constant acceleration.A Laser-velocity-measuring-system is included in the spectrometer,so ii can calibrate the absolate driving velocity.The Linear of constant aceeleration spectrometer is better than 0. 15% (when the velocity is ±43 ram/sec),the Line width<0. 26 mm/sec(α-Fe,the third and fourth Line).The Line width of constant velooity spectrometer<0. 27 mm/sec,She stability of the spectrometer is better than 0. 1%(24 hr)。更多还原
