    "abstract": "Using the concept of crossing state and the formalism of second quantization,\nwe propose a prescription for computing the density of arrivals of particles\nfor multiparticle states, both in the free and the interacting case. The\ndensities thus computed are positive, covariant in time for time independent\nhamiltonians, normalized to the total number of arrivals, and related to the\nflux. We investigate the behaviour of this prescriptions for bosons and\nfermions, finding boson enhancement and fermion depletion of arrivals.",
