Phys. Rev. Lett. 89, 025701 (2002) [4 pages]Modulation of the Nucleation Rate Preexponential in a Low-Temperature Ising SystemReceived 29 December 2001; published 19 June 2002 A metastable lattice gas with nearest-neighbor interactions and continuous-time dynamics is studied using a generalized Becker-Döring approach in the multidimensional space of cluster configurations. The preexponential of the metastable-state lifetime (inverse of nucleation rate) is found to exhibit distinct peaks at integer values of the inverse supersaturation. Peaks are unobservable (infinitely narrow) in the strict limit T→0, but become detectable and eventually dominate at higher temperatures. © 2002 The American Physical Society URL:
