Zero bias conductance peak (ZBCP) and gap features have been studied on tunneling interlayer spectra of the micron-sized NbSe 3 stacks of high quality. We show that temperature dependence and the shape of the ZBCP is self-consistently described by Bulaevskii theory of coherent interlayer tunneling of pocket carriers.
