Time windows of various nuclear methods for the observation of spin dynamical processes

  • S. Dattagupta
Invited Papers, Concluding Remarks


The applications of various hyperfine tools to the study of spin dynamical processes are reviewed. A few typical line shapes in the context of the Mössbauer effect and μSR derived from stochastic model calculations are discussed and the interplay of time scales associated with various processes in relation to the time window of a given probe is assessed.
