Description
The photonuclear reactions used for this isotopic analysis are as follows: 16O(γ,n)15O, threshold energy 15.7MeV and 18O(γ,p)17N, threshold energy 16.3 MeV. Oxygen-15 is a pure β+ emitter of half-life 2.03 minutes and nitrogen 17 presents a 4.2 second neutron emission. The method is based on the simultaneous measurement of the above radioactivities, the intensities being proportional to the respective quantities of oxygen-16 and oxygen-18 present in the irradiated sample. The possibilities of this new oxygen
