On the temperature dependence of the lifetime of thermally isolated metastable clusters

The temperature dependence of the lifetime of the thermally isolated metastable N 8 cubane up to its decay into N 2 molecules has been calculated by the molecular dynamics method. It has been demonstrated that this dependence significantly deviates from the Arrhenius law. The applicability of the fi...

Description
Summary:The temperature dependence of the lifetime of the thermally isolated metastable N 8 cubane up to its decay into N 2 molecules has been calculated by the molecular dynamics method. It has been demonstrated that this dependence significantly deviates from the Arrhenius law. The applicability of the finite heat bath theory to the description of thermally isolated atomic clusters has been proved using statistical analysis of the results obtained.
