ASCA observations of two X-ray transient pulsars, GRO J1008--57 and EXO 2030+375, are presented. Both sources were observed close to the end of an outburst, though not in quiescence. Pulse phase spectroscopy reveals, in both sources, that the spectrum flattens at the interpulse. This finding is consistent with the idea that the pulsar beam is pencil-shaped and that the interpulse corresponds to viewing the polar cap along the magnetic field lines.
