  text: 'We discuss the time evolution of the wave function which is the solution
    of a stochastic Schrödinger equation describing the dynamics of a free quantum
    particle subject to spontaneous localizations in space. We prove global existence
    and uniqueness of solutions. We observe that there exist three time regimes: the
    collapse regime, the classical regime and the diffusive regime. Concerning the
    latter, we assert that the general solution converges almost surely to a diffusing
    Gaussian wave function having a finite spread both in position as well as in momentum.
    This paper corrects and completes earlier works on this issue.'
