In this letter we suggest a scenario for simultaneous emission of gravitational-wave and \gamma -ray bursts ( GRBs ) from soft gamma-ray repeaters ( SGRs ) .
we argue that both of the radiations can be generated by a super-Eddington accreting neutron stars in X-ray binaries .
In this model a supercritical accretion transient takes back onto the remnant star the disk leftover by the hydrodynamic instability phase of a low magnetized , rapidly rotating neutron star in a X-ray binary system .
We estimate the rise timescale \Delta t _ { c } = 0.21 ms , minimum mass accretion rate needed to trigger the \gamma -ray emission , \dot { M } _ { \lambda } = 4.5 \times 10 ^ { 28 } g , and its effective associated temperature T _ { eff } = 740 keV , and the timescale for repeating a burst of \gamma -rays \Delta \tau _ { R } = 11.3 yr .
Altogether , we find the associated GW amplitude and frequency to be h _ { c } = 2.7 \times 10 ^ { -23 } / { ( Hz ) } ^ { 1 / 2 } and f _ { gw } = 966 Hz , for a source distance \sim 55 kpc .
Detectability of the pulses by the forthcoming GW anntenas is discussed and found likely .
