摘要：
Current theoretical predictions of the stopping range of fast electrons in the dense cores of fast-ignition fusion targets differ by about a factor of 2. Inconsistencies in the previous derivations are discussed and correct values of the stopping power, scattering coefficients, and ranges of fast electrons are obtained. Such more-accurate results can be used in theoretical studies of the ignition conditions and particles-in-cell and Monte Carlo simulations of the collisional electron transport in the plasma of fast-ignition targets. Convenient approximate relations for the stopping range and angular moments of the hot-electron distribution function are also obtained. (c) 2008 American Institute of Physics.
