Query: Kinetics of a Diffusive Capture Process: Lamb Besieged by a Pride of
  Lions   The survival probability, S_N(t), of a diffusing prey (``lamb'') in the
proximity of N diffusing predators (a ``pride of lions'') in one dimension is
investigated. When the lions are all to one side of the lamb, the survival
probability decays as a non-universal power law, S_N(t) is proportional to
t^{-beta_N}, with the decay exponent beta_N proportional to ln N. The crossover
behavior as a function of the relative diffusivities of the lions and the lamb
is also discussed. When N--->oo, the lamb survival probability exhibits a
log-normal decay, exp(-ln^2 t).
