摘要：

Average kinetic energy releases, [T], are calculated as a function of cluster size for (NH3)(n)H+ --> (NH3)n-1H+ + NH3. Two models are employed: (i) an RRKM/QET approach; (ii) evaporation from small particles. Both models reproduce the experimental maximum ("magic number") observed for [T] at n = 5.
