The general and explicit relation between the phase time and the dwell timefor quantum tunneling or scattering is investigated. Considering a symmetricalcollision of two identical wave packets with an one-dimensional barrier, herewe demonstrate that these two distinct transit time definitions give connectedresults where, however, the phase time (group delay) accurately describes theexact position of the scattered particles. The analytical difficulties thatarise when the stationary phase method is employed for obtaining phase(traversal) times are all overcome. Multiple wave packet decomposition allowsus to recover the exact position of the reflected and transmitted waves interms of the phase time, which, in addition to the exact relation between thephase time and the dwell time, leads to right interpretation for both of them.
