Abstract

The production of the therapeutic ^186gRe radioisotope by proton-induced ^natW(p,xn) reaction at the cyclotron C18/18 was investigated. The cyclotron is located at the A. Alikhanyan National Science Laboratory (Yerevan Physics Institute). The excitation function of the reaction in the proton energy range from the reaction threshold up to 18 MeV was measured. The measurements were carried out by the stack activation method followed by spectrometric analysis on the high purity germanium detector (HPGe). The activation of the obtained medical isotope ^186gRe was determined. The current experimental results are compared with theoretical calculations performed by TALYS 1.95 and EMPIRE 3.2 codes, as well as with the other available experimental data. It has been shown the possibility of production of the above-mentioned radionuclide on the cyclotron C18/18 in the amount required for medical purposes using an enriched target.

回旋加速器C18 / 18质子束产生186g Re医用同位素

摘要

研究了在回旋加速器C18 / 18上质子诱导的^nat W（p，xn）反应产生的治疗性^186g Re放射性同位素。回旋加速器位于A. Alikhanyan国家科学实验室（耶烈万物理学院）。在从反应阈值到18 MeV的质子能量范围内，测量了反应的激发函数。通过堆叠激活方法进行测量，然后在高纯度锗检测器（HPGe）上进行光谱分析。活化所得医学同位素^186g重新确定。将当前的实验结果与TALYS 1.95和EMPIRE 3.2代码进行的理论计算以及其他可用的实验数据进行比较。已经显示有可能使用富集靶在回旋加速器C18 / 18上产生医学上所需量的上述放射性核素。
