This experiment featured an emitting iron-57 nucleus that was placed in a crystal lattice in order to counteract the Mossbauer Effect.
This experiment featured an emitting iron-57 nucleus that was placed in a crystal lattice in order to counteract the Mossbauer Effect. That iron sample was placed in a speaker, and the speaker was oscillated with a frequency between 10Hz and 50Hz. The effect in question competes with a Doppler Shift due to Special Relativity, so the experimenters sought to find the point at which the effects cancelled. Performed at Harvard's Jefferson Laboratory, this experiment placed the source near the top of a tower and a scintillation counter near the bottom. For ten points, identify this classic doubly- eponymous test of the gravitational redshift.
