This paper continues the authors' previous study [R. Murray and R. Pego, SIAM J. Math. Anal., 48:2819-2842, 2016] of the trend toward equilibrium of the Becker-Döring equations with subcritical mass, by characterizing certain fine properties of solutions to the linearized equation. In particular, we partially characterize the spectrum of the linearized operator, showing that it contains the entire imaginary axis in polynomially weighted spaces. Moreover, we prove detailed cutoffestimates that establish upper and lower bounds on the lifetime of a class of perturbations to equilibrium.
