可测量的裂变径迹封闭长度分布与重离子打孔参数的关系

Relationship between measured distributions of fission track length and parameters of heavy ion tracks

为了得到真实的裂变径迹封闭长度分布，需要对重离子径迹密度、孔径及裂变径迹长度进行几率归一修正。对重离子蚀刻径迹与裂变径迹相重叠的几率进行了理论计算及MonteCarlo模拟。

The theoretical calculations and Monte-Carlo Simulatiuons of the relationshipbetween the measured distributions of fission track length and the parameters ofheavy ion tracks have been carried out. It is shown that the measured distributions offission track length are strongly dependent on the parameters of heavy ion trackswhich are used as the passage for etching out the latent tracks of 238U fissionfragments.
