A GINGA OBSERVATION OF THE X-RAY PULSAR 4U-0352+30

4U 0352+30 (X Persei) is a low-luminosity binary X-ray pulsar with a p ulse period of 835 s. We present timing and spectral analysis of a Gin ga observation of X Persei from 1990 January 26 to January 29. The obs ervation shows the peculiar spectral behavior of X Persei: the pulse-a veraged hardness ratio exhibits a sharp hardening episode at phase min imum of the light curve. In order to explain the shape of the observed hardness ratio, we discuss the possible geometry of the emitting regi on. Simple models of fan emission from a hollow accretion column can r eproduce the qualitative features of the observed light curve and hard ness ratio.
