    "abstract": "This paper compares the proposal made in previous papers for a quantum\nprobability distribution of the time of arrival at a certain point with the\ncorresponding proposal based on the probability current density. Quantitative\ndifferences between the two formulations are examined analytically and\nnumerically with the aim of establishing conditions under which the proposals\nmight be tested by experiment. It is found that quantum regime conditions\nproduce the biggest differences between the formulations which are otherwise\nnear indistinguishable. These results indicate that in order to discriminate\nconclusively among the different alternatives, the corresponding experimental\ntest should be performed in the quantum regime and with sufficiently high\nresolution so as to resolve small quantum efects.",
