Nuclear Forward Scattering
one bound nucleus with only one transition line.
The amplitudes and phases of the relevant spectral components of incident E i(w) and scattered Es(w) radiation are related
of the scattered radiation component
The kinetics i.e. the time response or response function a0(t) of an individual nucleus to a d-like excitation (the synchrotron radiation pulse) is given by the Fourier transformation:
In general the time response of the whole system is a convolution of the incident wave packet and the response function of the scatterer.
