Abstract
Radionuclides are often used in medicine diagnosis, clinical chemistry, molecular biology and other life
sciences fields. The isotopic neutron sources of 241Am-9Be and 239Pu-9Be and the cyclotron are normally
used for the production of some medical interest radioisotopes such as: 116mIn,56Mn, 198Au, 61,64Cu. The
radioisotope 64Cu is both a positron and a beta emitter and is already used for labelling of PET imaging
radiopharmaceuticals. In order to study the production of 64Cu, the stacks consisting of 64Zn foils, Ti
monitor foils and Al catcher foils were irradiated at a Scanditronix MC40 cyclotron with a 19.5 MeV
deuteron beam energy. The activities of the various product isotopes in the foils were analysed by ?-
spectrometry with HPGe detectors. The average deuterosn energies in the foils were calculated with the
SRIM 2003 code. Theoretical excitation functions calculated with the Alice-91code were compared with the
experimental ones and a reasonable agreement was found. This study provides the first experimental data
regarding the deuteron induced 64Zn(d,2p)64Cu reaction on enriched 64Zn.
