Reactions on Zr induced by alpha-particles with energies up to 60 MeV were studied by stacked foils method. Production cross-sections for zirconium (Zr), niobium (Nb) and molybdenum (Mo) radionuclides were determined and thick target yields were calculated. The possibility of obtaining Nb through the intermediate formation of Mo is discussed. It is possible to obtain 19.6 MBq/(μA·h) Mo upon saturation, that leads to 4 MBq/(μA·h) Nb after decay.
采用叠层箔片法研究了能量高达60 MeV的α粒子对Zr的反应。测定了锆(Zr)、铌(Nb)和钼(Mo)放射性核素的生成截面,并计算了厚靶产额。讨论了通过Mo的中间形成获得Nb的可能性。饱和时可获得19.6 MBq/(μA·h)的Mo,衰变后可产生4 MBq/(μA·h)的Nb。
