Structure and spatial distribution of Ge nanocrystals subjected to fast neutron irradiation
Structure spatial distribution fast neutron irradiation
2010/11/23
The influence of fast neutron irradiation on the structure and spatial distribution of Ge nanocrystals (NC) embedded in an amorphous SiO2 matrix has been studied. The investigation was conducted by me...
Displacement damage dose approach to analyze ion irradiation effects on homemade GaAs/Ge solar cells
GaAs/Ge solar cells displacement damage dose carbon ion proton irradiation
2009/8/14
Displacement damage dose is applied to analyze the irradiation effects of 2 MeV carbon ions and 0.28~20 MeV protons on homemade GaAs/Ge solar cells. The NIEL for each ion is modified by taking into a...
偶偶Ge和Se同位素核的形变HF态及负宇称带研究
形变HF态 角动量投影 单粒子能谱 负宇称带
2009/5/25
将具有负宇称的fp轨道空间扩大到包含具有正宇称的1g9/2轨道,采用修正的表面δ相互作用,对64Ge,66Ge,68Ge,70Se,72Se和74Se等6个偶偶核做了形变HF计算.得到了基态和一些激发态的解.同时,还用近似角动量投影形变Hartree-Fock(PDHF)方法,对64Ge和74Se进行了能谱计算,得到其正、负宇称带的解,计算结果与实验谱基本一致.
用落下灰Ge(Li)γ能谱中~(95)Zr-~(95)Nb谱峰估算核爆日期
谱峰估算 灰Ge(Li)γ能谱
2008/12/11
文报告了用核爆后放射性落下灰Ge(Li)γ能谱中,~(95)Zr-~(95)Nbγ射线峰面积比估算核爆日期的方法。即利用~(95)Zr与~(95)Nb在某测量时刻的γ辐射比来估算核爆日期。研究了不同的峰面积计算方法对估算结果的影响。用我国1976年元月23日核试验放射性落下灰的Ge(Li)γ能谱进行检验,结果表明,用R_(03)=~(95)Zr(757 keV)/~(95)Nb(766 keV)和...
