Abstract
The excitation function of the natCu(3He,x)65Zn nuclear reaction was measured from its threshold up to 53 MeV incident energy relative to the natTi(3He,x)48V monitor reaction by using the conventional stacked foil activation technique combined with HPGe γ-ray spectrometry. Our result is systematically higher than the IAEA recommendation, and more experimental works are desired especially above 25 MeV.
Highlights
Production of medical radionuclides via accelerator pathway and/or via charged-particle induced nuclear reactions shows great attention in recent time, and their production cross-sections are important nuclear data to identify efficient production routes
The present work concerns the measurement of the natCu(3He,x)65Zn excitation function from its threshold up to 53 MeV incident energy by using the conventional stacked foil activation technique combined with HPGe γ-ray spectrometry
The IAEA recommended monitor reaction crosssection of natTi(3He,x)48V (σ =163 mb at E3He= 55.27 MeV) [1, 13] was used to determine the beam intensity at the front positioned foil, and we considered that the beam flux was a constant throughout the whole stack
Summary
Production of medical radionuclides via accelerator pathway and/or via charged-particle induced nuclear reactions shows great attention in recent time, and their production cross-sections are important nuclear data to identify efficient production routes. The accuracy of the chargedparticle induced nuclear reaction cross-sections largely depends on the precise determination of the accelerated particle beam parameters such as beam intensity. Monitoring of beam intensity can be done in several ways, and some well-studied nuclear reactions (monitor reactions) could be used with high accuracy in this purpose. Understanding the importance of beam parameter monitoring during irradiation, a number of monitor reactions are recommended by the International Atomic Energy Agency [1], where the natCu(3He,x)65Zn is included as one of the recommended reactions to be used for 3He beam monitoring purpose. The present work concerns the measurement of the natCu(3He,x)65Zn excitation function from its threshold up to 53 MeV incident energy by using the conventional stacked foil activation technique combined with HPGe γ-ray spectrometry
