摘要：

We present results of isothermal molecular-dynamics calculations for Na8 microclusters. The Born-Oppenheimer dynamics is calculated using a many-body potential developed by Tomanek and coworkers. We analyzed the system in a temperature range from 25 to 1500 K. The Na8 cluster seems to undergo two phase transitions, a solid-glass transition at almost-equal-to 100 K, and a melting transition at T almost-equal-to 800 K.
