Abstract
The Be X-ray binary A 0535+26 was observed by OSSE on CGRO during a gi ant outburst in February 1994. Grove et al. (1995) detected a cyclotro n absorption feature at 110 keV in the pulse phase averaged spectrum. In this paper, we present the analysis of the dependence of the pulse shape on energy and intensity, and discuss the development of the puls e averaged spectral shape during the observation.
