Abstract We have observed scattering of synchrotron radiation by the 9.4-keV nuclear resonance of gaseous {sup 83}Kr. In a gas, there is no recoilless absorption (no Moessbauer effect). A cell of krypton gas (natural abundance, 12% {sup 83}Kr) was placed after a Si(111) monochromator. Incoherent resonant nuclear scattering, 0.3 cts/s, was separated from nonresonant electronic scattering, 7{times}10{sup 7} cts/s, using the time resolution of an avalanche diode detector. The resonance energy was found to be 9403.5{plus_minus}1.8 eV. The time dependence of the scattered radiation agrees with a previous measurement of the excited-state lifetime.
