Abstract
Abstract We show that the giant flares of soft gamma ray repeaters ( E ∼10 44 erg) can push the inner regions of a fall-back disk out to larger radii by radiation pressure, while matter remains bound to the system for plausible parameters. The subsequent relaxation of this pushed-back matter can account for the observed enhanced X-ray emission after the August 27 th giant flare of SGR 1900+14.
