The Instrumentation Project is introducing Mossbauer spectroscopy into upper-division modern physics and nuclear physics laboratories in the Department of Physics and Astronomy. This type of experiment can be very useful in directly exposing students to basic concepts in quantum mechanics. A series of experiments is focusing on (1) observation of quantum uncertainty; (2) observation of changes in the nuclear charge distribution through measurement of the isomer shift; (3) observation of nuclear Zeeman splitting and measurement of the internal hyperfine field strength from the level splitting; and (4) observation of quantum uncertainty through detection of virtual states produced by RF/gamma-ray multiphoton absorption. Entrance and exit examinations are being conducted in the laboratories to assess the educational outcomes. Also, Mossbauer experiments are being used in cooperation with the Departments of Chemistry and Geology to expose students to the use of this spectroscopic technique in characterizing the chemical composition of materials.

仪器项目正在将穆斯堡尔谱学引入物理和天文学系的高级现代物理和核物理实验室。 这种类型的实验在直接让学生接触量子力学的基本概念方面非常有用。 一系列实验的重点是：（1）观察量子不确定性;（2）通过测量同质异能素位移观察核电荷分布的变化;（3）观察核塞曼分裂并测量能级分裂产生的内部超精细场强度;（4）通过检测RF/伽马射线多光子吸收产生的虚态观察量子不确定性。在实验室进行入学和毕业考试，以评估教育成果。 此外，穆斯堡尔实验正在与化学和地质学系合作，让学生接触到这种光谱技术在表征材料化学成分方面的应用。
