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 25 Zi2Zt2At keV.
