Abstract
A different relative diffusion coefficient for electrons interacting with coherent, localized Langmuir wave packets is proposed. It is shown that the coherent, localized wave packets can drive the formation of clumps in phase space, and only when the relative velocity is zero does the lifetime of clumps diverge logarithmically, with the relative positions of the constituents getting closer to one another.Keywords
