Radiation defect kinetics modeling is used to describe ion tracks in lithium fluoride crystals. According to the track geometry, suggested model takes into account diffusion currents of point defects and their drift in the temperature and elastic fields, caused by thermal spike. Due to the different dilatation signs of vacancies and interstitials, the induced stress field produces the opposite forces, squeezing out the interstitials, whereas the vacancies are rather confined.

Resulting anion depletion in the track center can explain formation of the track core, which was observed with SAXS, chemical etching, AFM and other techniques, for heavy projectiles when the linear energy transfer exceeds a threshold of ~10 keV/nm. The anion interstitials can form aggregates, which were observed with VUV absorption spectroscopy and NMR studies, aside the track center.

辐射缺陷动力学模型用于描述氟化锂晶体中的离子轨迹。根据轨道的几何形状，建议的模型考虑了点缺陷的扩散电流以及它们在温度和弹性场中由热尖峰引起的漂移。由于空位和间隙的膨胀符号不同，诱导应力场会产生相反的力，从而将间隙挤出，而空位则受到限制。

当线能量转移超过〜10 keV / nm的阈值时，对于重弹丸，在轨中心产生的阴离子耗尽可以解释轨芯的形成，这是通过SAXS，化学蚀刻，AFM和其他技术观察到的。阴离子间隙可形成聚集体，轨道中心旁可通过VUV吸收光谱法和NMR研究观察到。
