تفاعلات الذرة الحارة الناتجة عن التفاعل (n,γ) في مركب الهولميوم Tris (2,2,6,6-tetramethyle-3,5-heptanedionato) Holmium (III)

The behavior of a recoiled 166Ho resulting from the reaction 165Ho(n,γ) 166Ho in the compound Tris (2,2,6,6-tetramethyle-3,5-heptanedionato) Holmium(III) was investigated. Irradiation was carried out in a low flux research reactor (the Syrian Miniature Nuclear Source Reactor MNSR) with a maximum thermal neutron flux of 1×1012 n.cm-2.s-1. Chemical separation methods were developed to separate the recoil product from the irradiated compound. It was found that the paper chromatography gave the best results where the compound was developed with toluene. The study showed that the retention value of holmium 166Ho was equal to 45%. It was also found that the process of purification and the irradiation of samples in an inert atmosphere had a neglected impact on the retention value of the studied compound. This was attributed to the presence of oxygen in the structure of the molecule, where it is released during the nuclear recoil process and play scavenger role.
