The proton and deuteron induced reaction have a great interest for the assessment of induced radioactivity of accelerator components. The IFMIF (International Fusion Material Irradiation Facility) accelerator needs such a data for estimation of the potential radiation hazards from the accelerating cavities and beam transport elements (Al, Cu, Fe, Cr, Nb). The cross sections are needed in the energy range from the threshold (2--10 MeV) up to 40 MeV both for deuterons and protons. In order to investigate the first important nuclides relevant to the IFMIF, we have carried out the irradiation experiment with the variable-energy cyclotron U-120M of the Nuclear Physics Institute Rez. The production cross section of the nuclides 28-Al, 27-Mg, 24-Na from reaction on 27-Al, further - the nuclides 64-Cu, 63-Zn, 62-Zn from reactions on 63-Cu and the nuclides 65-Zn, 65-Ni from reactions on 65-Cu were investigated by irradiation of aluminium and cuprum (natural isotope abundance) foil by deuteron beam of 20 MeV energy. The stacked-foil technique was utilized. The absolute values of cross sections were calculated from the induced activities measured by calibrated HPGe detectors. The gamma-rays from the irradiated foils were analyzed by the DEIMOS code. The comparison of present results with data of other authors and with the prediction of different libraries is discussed.
