摘要
The fluorine concentration of chemically enriched hydroxylapatite (Ca10(PO4)6(OH)2) was measured by means of PIGE using the nuclear reactions F-19(p, p' gamma)F-19 and F-19(p, alpha-gamma)O-16. The experiments were done in-two runs with 1.68 and 2.15 MeV proton incidence. The results determined with inelastic scattering are in good agreement in the two runs. The samples are suitable as new fluorine standards in the ppm region to study the fluorine content in tooth enamel.
