低能锗核燃料电离效率的研究

Ionization Efficiency Study for Low Energy Nuclear Recoils in Germanium

D. Barker, W. -Z. Wei, D. -M. Mei, C. Zhang

摘要:

我们利用锗-72的内转换($E_0$跃迁)间接测量了锗的低能核反冲。结合可靠的蒙特卡罗程序包(我们在其中实施了内部转换过程),将数据与Lindhard($k$ =0.159)和Barker-Mei模型进行了比较。形状分析表明,这两个模型同意以及在该地区的数据在4%以内的利益。由形状分析得到的核反冲的最可几值(MPV)为17.5 keV,平均程长为0.014 $μ$ m。

英文摘要:

We used the internal conversion ($E_0$ transition) of germanium-72 to indirectly measure the low energy nuclear recoils of germanium. Together with a reliable Monte Carlo package, in which we implement the internal conversion process, the data was compared to the Lindhard ($k$=0.159) and Barker-Mei models. A shape analysis indicates that both models agree well with data in the region of interest within 4%. The most probable value (MPV) of the nuclear recoils obtained from the shape analysis is 17.5 keV with an average path-length of 0.014 $μ$m.
