Moessbauer Effect Lab
Mössbauer Effect Using Co57
Includes a general introduction to spectroscopy and details of Mossbauer technique. Discusses the nuclear properties to be measured: the Zeeman effect, quadrupole splitting, and the isomer shift.
This section is a walkthrough of the specific components used in this experiment, and a broad overview of the total setup and how it works.
Further details needed to understand how the SCA and Counter modules function, and a study of the Cobalt 57 spectrum.
This section discusses an additional method of using the SCA ('scanning SCA') to study the 14.4 keV peak and correctly calibrate the SCA for the final setup.
The Mossbauer setup is very sensitive to the amount of sample material used in the absorber.
Taking data with the setup; analysis of the data.
Here are some (potentially) helpful and unhelpful oddities and other asides about the methods lab Mossbauer setup.
