本文提出了一种分析慢离子在金属中运动阻止本领的自由参数原子轨道线性组合方法。该方法适用于He在碱金属中运动的情况。平均阻止权力，他提出了良好的协议与本地密度近似计算。我们的结果表明，重要的变化，阻止能力的通道原子就其平均值
A free-parameter linear-combination-of-atomic-orbitals approach is presented for analysing the stopping power of slow ions moving in a metal. The method is applied to the case of He moving in alkali metals. Mean stopping powers for He present good agreement with local-density-approximation calculations. Our results show important variations in the stopping power of channeled atoms with respect to their mean values
