Abstract X-ray source GX301-2 was observed with scintillation proportional counters in binary phase 0.90 to 0.05. Intense iron fluorescent emission and sharp iron K absorption edge appeared in all spectrum including flare, which occured on JD 2445814.6. The equivalent width are linearly correlated with column density and this can be interpreted by a simple model that cold isotropic gas surround compact source. Pulse fraction also changed inversely correlated way with column density which suggest smearing by scattering of x-rays in the reprocessing medium. Averaged iron K absorption edge energy was 7.36±0.02 keV.
