NUCLEAR-EXCITATION OF FE-57 IONS IN HYDROCHLORIC-ACID SOLUTION USING SYNCHROTRON-RADIATION

Nuclear resonant excitation of Fe-57 ions in a hydrochloric acid solut ion has been observed successfully for the first time by the use of a pulsed source of synchrotron radiation with a time-resolved detection system. The experimental results can be interpreted in term of the con cept of recoiled nuclear resonance and dynamics of atomic motions in a solution. It has thus been proven that synchrotron radiation studies of nuclear resonance phenomena can be performed not only in the solid state, but also in liquid and gas states.
