Stationary diffraction pattern of cBN powder

Caption

Figure 1: a) Stationary diffraction pattern of cBN powder, integrated over the Debye-Scherrer rings, measured with femtosecond x-ray pulses as a function of the diffraction angle 2θ. b) Transient intensity change of the (111) diffraction signal after impulsive Raman excitation with femtosecond 800-nm pump pulses (solid circles, 1 ps temporal binning). Open symbols: same data with shifted 1-ps binning. Green line: steplike fit superimposed on oscillations with a frequency of 250 GHz.
