Observation of nuclear excitation of F by synchrotron radiation

Harami, Taikan; Yoda, Yoshitaka*; Fujiwara, Mamoru*

The nuclear excitation of F was first observed by synchrotron radiation in the beamline of SPring-8. The excitation energy, 110 keV, is the highest energy that was observed by synchrotron radiation so far. In spite of the low detector efficiency and the relatively short lifetime of 0.6 ns, the identification of the nuclear excitation was successful. The F nuclear excitation will provide a specific tool for the detection, identification and quatification of fluorine-containing drugs. In the field of elementary particle physics, the parity non-consevation effect can now be studied in nuclear excitation processes in F.
