摘要：

We have observed scattering of synchrotron radiation by the 9.4-keV nuclear resonance of gaseous Kr83. In a gas, there is no recoilless absorption (no Mössbauer effect). A cell of krypton gas (natural abundance, 12% Kr83) was placed after a Si(111) monochromator. Incoherent resonant nuclear scattering, 0.3 cts/s, was separated from nonresonant electronic scattering, 7×107 cts/s, using the time resolution of an avalanche diode detector. The resonance energy was found to be 9403.5±1.8 eV. The time dependence of the scattered radiation agrees with a previous measurement of the excited-state lifetime. © 1995 The American Physical Society.
