Abstract

A measuring device (detector) of the coordinate of quantum particle as an absorbing wall that cuts off the particle's wave function was defined. The trace that absorbed particles leave on the detector was identified as the absorption current density on the detector. The density was calculated from the solution of Schrödinger's equation with a reflecting boundary at the detector. The resulting theory revealed that the quantum-mechanical collapse of the wave function was replaced by the collapse of probability distribution after observation.
