金属团簇中的电子-声子耦合和非谐效应
Electron--phonon coupling and anharmonic effects in metal clusters
摘要：
考虑了带电钠团簇离子核在平衡形状附近的谐振周期。据发现，这些期间的数量级的实验测得的弛豫时间的等离子体激元，这表明的重要性的电子-离子耦合和应力的作用所发挥的电子-声子相互作用中的耗散的等离子体激元能量。简要讨论了该过程与裂变的关系。
英文摘要：
The periods of the harmonic oscillations of the ion core of charged sodium clusters around the equilibrium shapes are considered. It is found that these periods are of the order of magnitude of the experimentally measured relaxation times of the plasmons, which suggests the importance of the electron-ion coupling and stresses the role played by the electron-phonon interaction in the dissipation of the plasmon energy. The relation of the process to fission is briefly discussed.
