摘要

通过堆叠箔片法研究了能量高达 60 MeV 的阿尔法粒子在铌锆上诱发的反应。确定了锆（88,89,95Zr）、铌（90,92m,95m,95,96Nb）和钼（90,93m,99Mo）放射性核素的生成截面，并计算了厚靶产率。讨论了通过 90Mo 的中间形成获得 90Nb 的可能性。饱和后可获得 19.6 MBq/(μA-h) 90Mo，衰变后可获得 4 MBq/(μA-h) 90Nb。

Alpha-particles induced reactions on natZr as a pathway of medical 90Nb production

Reactions on ^natZr induced by alpha-particles with energies up to 60 MeV were studied by stacked foils method. Production cross-sections for zirconium (^88,89,95Zr), niobium (^{90,92m,95m,95,96}Nb) and molybdenum (^90,93m,99Mo) radionuclides were determined and thick target yields were calculated. The possibility of obtaining ⁹⁰Nb through the intermediate formation of ⁹⁰Mo is discussed. It is possible to obtain 19.6 MBq/(μA·h) ⁹⁰Mo upon saturation, that leads to 4 MBq/(μA·h) ⁹⁰Nb after decay.

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
