Reference: Experiments in Modern Physics (p.385-p.399) I. Introduction In this experiment you will observe the Mossbauer effect in a non-magnetic material (stainless steel) and then use the effect to measure the magnetic moment of the nucleus of a magnetic material (Fe57). The Appendix contains a brief discussion of the Mossbauer effect. II. Counter The detector … Read more

Read before class: Textbook section 8.3.1 and 8.3.4 A short discussion of X-ray Diffraction from crystals such as NaCl I. Introduction From diffraction patterns, one can measure the average spacings between layers or rows of atoms; determine the orientation of a single crystal or grain; find the sub-atomic (crystal) structure of an unknown material and … Read more

Reference: Melissinos, Experiments in Modern Physics (p.399-409) I. Introduction The surface of the earth is constantly struck by cosmic ray particles arriving from high in the atmosphere. Most of the surface flux is due to muons resulting from the decay of pions produced by high altitude interactions of the primary cosmic rays (mostly protons) with … Read more
