  Motivated by a recent prediction [Com. Phys., 6, 195 (2023)] that
time-of-flight experiments with ultracold atoms could test different
interpretations of quantum mechanics, this work investigates the arrival times
predicted by the stochastic interpretation, whereby quantum particles follow
definite but non-deterministic and non-differentiable trajectories. The
distribution of arrival times is obtained from a Fokker-Planck equation, and
confirmed by direct simulation of trajectories. It is found to be in general
different from the distribution predicted by the Bohmian interpretation, in
which quantum particles follow definite deterministic and differentiable
trajectories. This result suggests that trajectory-based interpretations of
quantum mechanics could be experimentally discriminated.
