Abstract
The contribution of weakly magnetized (B similar to 10(9) G) neutron s tars accreting the interstellar medium to the diffuse X-ray emission o bserved in the Galactic center is investigated, It is shown that, unde r rather conservative assumptions about the neutron stars and gas dist ributions, the accretion luminosity can account for a sizable fraction , possibly most, of the detected X-ray flux in the 2.5-7 keV band. In particular, model results are compared with Granat data and show a gen eral agreement in both the Bur energy and radial distributions.
