Spectrum averaged cross sections for the 64 Zn(n, p) 64 Cu, 67 Zn(n, p) 67 Cu and 89 Y(n, p) 89 Sr reactions were measured using a 14 MeV d(Be) neutron source. In each case a clean radiochemical separation was performed and the radioactivity of the product was determined via highresolution γ -ray spectrometry or anticoincidence β − counting. The cross sections are three to five times higher than with a fission neutron spectrum. It is postulated that at an intense fast spectral neutron source, e.g. a spallation source, it would be advantageous to use an (n, p) reaction: GBq amounts of 64 Cu and 67 Cu could be produced in one hour irradiation and of 89 Sr in about one day irradiation.
