Abstract

A new method is proposed for determining the maximum and FWHM of the excitation function of a photonuclear reaction with dominating giant dipole resonance (GDR). The technique is based on joint application of experimental study, analytical model and Monte Carlo simulations. A special regime for activation of an isotopic target by bremsstrahlung radiation, as well as a data processing algorithm providing an explicit connection between the target partial activity and Lorentz parameters of GDR have been developed. The novel approach is used to determine the cross section of the ⁴⁸Ti(γ,p)⁴⁷Sc reaction. A way for verifying the obtained data is offered.

巨偶极子共振振幅和宽度的一种计算方法。在48Ti上光核生产47Sc的截面

提出了一种确定巨偶极子共振（GDR）占主导地位的光核反应激发函数的最大值和最大功率的新方法。该技术是基于实验研究、解析模型和蒙特卡罗模拟的联合应用。本文提出了一种利用轫致辐射激活同位素靶的特殊机制，以及一种数据处理算法，该算法提供了靶部分活度与GDR洛伦兹参数之间的明确联系。该方法用于测定48Ti(γ,p)47Sc反应的截面。给出了一种验证所得数据的方法。

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.
