镓同位素的光核反应截面

Photonuclear Reaction Cross Sections for Gallium Isotopes

Serkan Akkoyun, Tuncay Bayram

摘要:

光子诱导反应又称光核反应,在核物理、辐射物理及相关领域中具有重要的意义。由于我们计划将来利用临床直线加速器产生的韧致辐射光子对镓靶进行光核反应,因此本研究采用TMSPS 1.2计算程序计算了光子激活后的中子(光致中子(γ,xn))和质子(光致质子(γ,xn))产生截面。目标核被认为是镓,它有两个稳定的同位素,69 Ga和71 Ga。结果表明,在有限的文献值范围内,计算结果是一致的。此外,预平衡和复合过程对总截面的贡献进行了研究。

英文摘要:

The photon induced reactions which are named as photonuclear reactions have a great importance in many field of nuclear, radiation physics and related fields. Since we have planned to perform photonuclear reaction on gallium target with bremmstrahlung photons from clinical linear accelerator in the future, the cross-sections of neutron (photo-neutron (γ,xn)) and proton (photo-proton (γ,xn)) productions after photon activation have been calculated by using TALYS 1.2 computer code in this study. The target nucleus has been considered gallium which has two stable isotopes, 69Ga and 71Ga. According to the results, we have seen that the calculations are in harmony in the limited literature values. Furthermore, the pre-equilibrium and compound process contributions to the total cross-section have been investigated.
