摘要：

It had been proposed earlier that the hard X-ray and gamma-ray radiation of the Be/X-ray system LSI +61 degrees 303 could be due to inverse Compton scattering of optical photons from the Be star by the same electron population which also produces the radio emission. Recently, Apparao (2001) has calculated this inverse Compton emission in more detail, and predicted that the X-ray spectrum should show a break at around 20 keV. We investigated archival RXTE data, but do not find such a break in the 2-25 keV range. The implications of this finding are shortly discussed.
