    "abstract": "We analyze in mathematical detail, within the framework of the QMUPL model of\nspontaneous wave function collapse, the von Neumann measurement scheme for the\nmeasurement of a 1/2 spin particle. We prove that, according to the equation of\nthe model: i) throughout the whole measurement process, the pointer of the\nmeasuring device is always perfectly well localized in space; ii) the\nprobabilities for the possible outcomes are distributed in agreement with the\nBorn probability rule; iii) at the end of the measurement the state of the\nmicroscopic system has collapsed to the eigenstate corresponding to the\nmeasured eigenvalue. This analysis shows rigorously how dynamical reduction\nmodels provide a consistent solution to the measurement problem of quantum\nmechanics.",
