高能带电粒子库仑对数量子力学效应研究

 先进燃料D-3He聚变产生的高能带电粒子在本底等离子体中慢化时间的准确性直接影响到能量平衡和高能离子压强的计算结果。结果表明：高能带电粒子与本底等离子体的离子相互作用的库仑对数量子力学效应明显。应使用高能带电粒子库仑对数力学效应来研究聚变产生的高能端部粒子慢化过程；能量大于等于25Z²_iZ²_iA_i keV的高能粒子与本底等离子体中离子的相互作用库仑对数最好也使用量子截断。

Quantum mechanical effects on Coulomb logarithm for high energy particles

For high energy particles produced in advanced fuel D-3He fusion reactions,the calculation accuracy of their slowing down time has a direct and notable impact on energy balance and pressure of high energy particles during the initial phase of thermalization processes in the background plasma.Analysis shows prominent Coulomb logarithm quantum mechanical effects of the reciprocity between the high energy particles and the ions of background plasma.It is better to make use of the proper Coulomb logarithm quantum mechanical effect at the high energy end in studying the particles' slowing process and take quantum truncation to process Coulomb logarithm of the reciprocity between the high energy particles and the ions of background plasma also,as energy is more than 25Z2iZ2tAt keV.
