The time response of resonant nuclei in a rotating sample coherently excited by synchrotron radiation pulses maps to an angular scale. At sufficiently high rotational speeds, the temporal evolution of the nuclear decay can be recorded with a position sensitive detector. This has been demonstrated by nuclear resonant scattering of synchrotron radiation from a [sup 57]Fe metal foil rotating at 10 kHz. The method has the potential to yield time resolutions of a few 10 ps, thus overcoming principal limits of existing techniques. © 2001 American Institute of Physics.
